Some suggestions.

I found the following text with some examples that might help:

"A historical materialist interpretation of this separation of politics from economics is that the state embodies political alienation due to the fact that its very existence as a specialised political entity 'testifies to the estrangement of community and communal powers from the daily lives and productive activities of people within capitalist social reality' (Ruper, 1993:76). According to Ruper, the political economy of neoliberalism is therefore more than just an emphasis on markets and non-intervention..."

A bit of a combination of others' suggestions, but I thought I'd add some more information on the topic.

The asker's text refers to a "neoliberal morality" and a "derecho des-solidarizado."

In the detailed Wikipedia article about neoliberalism, there is an interesting critique:

"American scholar and cultural critic Henry Giroux alleges that neoliberal market fundamentalism fosters a belief that market forces should organize every facet of society, including economic and social life, and promotes a social Darwinist ethic that elevates self-interest over social needs. Marxist geographer David Harvey argues that neoliberalism promotes an unbridled individualism that is harmful to social solidarity."

The meaning of the word derecho, according to the RAE, would be as follows:

"13. m. Conjunto de principios y normas, expresivos de una idea de justicia y de orden, que regulan las relaciones humanas en toda sociedad y cuya observancia puede ser impuesta de manera coactiva."

Thus, it describes a legal system that lacks social solidarity, which results in societal alienation (for example, an argument can be made that this is what's happening in the US due to its brutal capitalism, which has been clearly exposed during the COVID crisis.)

I find the word "des-solidarizado", interestingly enough, only in Argentinean texts, perhaps because of the negative connotations that the term "neoliberalism" has had in South America in the not-so-distant history (due to Augusto Pinochet's economic reforms in Chile in the 80s.) Perhaps this is why Argentina has always tended to be more socialistic in its approach to governing. Thus, anything that moves away from being in solidarity with society would be "des-solidarizado," thereby emphasizing the lack of solidarity.

In the link https://bit.ly/2LJF0vX, the book La era de la desolación: ética y moral en la Argentina de fin de siglo refers to this concept as follows:

Pero en uno u otro caso, y de acuerdo con su significación etimológica, "desolar" significa precisamente des-solidarizar o romper la solidaridad entre elementos que hasta ese momento estaban juntos; todo lo contrario de con-solidar. Algo sólido, justamente, es una cosa cuyas partes son difíciles de separar o disolver, romper o corromper, como cuando hablamos de una "sólida amistad". La desolación no es entonces un sentimiento característico de la "condición humana", como algunos cultores del "mal metafísico" pretenden, sino, al contrario, la experiencia de un individuo reducido a "condiciones inhumanas" de vida, al aislamiento y la ruptura de toda solidaridad comunitaria.

I would suggest that they are talking about the effects of alienation or the lack of social solidarity. "Solidarity" on its own can mean various things, but "social solidarity" refers specifically to the phenomenon of wider societal participation and responsibility for the good of all. The breaking (or "ruptura") of this concept would result in societal alienation.

I would translate una moral neoliberal y un derecho “des-solidarizado” as follows:

... a neoliberal morality and an alienating legal system ...

or

... a neoliberal morality and a legal system lacking social solidarity ...

1. There are plenty (well, quite a few) examples online of 'desolidarized' 'de-solidarized' 'desolidarised' and 'de-solidarised".
In view of that, it seems...er...illogical to not use the word in English.
2. There are more examples in English online than in Spanish.
3. The word in Spanish seems to come from the English, not vice-versa.
4. The writer seems to be quoting Axel Honneth, a German philosopher who writes in English:
