An alternative to changing the adjective to a noun, you could insert a pronoun which the adjective could modify. "He doesn't like it dirty"

Without further context, it is impossible to know what the speaker intended to say with this grammatically incorrect sentence. For it to make any sense at all, you must first correct its grammar. There are different ways to do this and they lead to differing interpretations. Also, "dirty" has various colloquial meanings: "He doesn't like dirt" "He doesn't like dirty things (or places)" "He doesn't like indecent things" "He doesn't like dishonesty" "He doesn't like doing indecent things" "Like" can also be a filler word with no effect on the meaning of the sentence: "He doesn't (like) do immoral things"

He doesn't like dirt is correct

Hi, no that doesn't really work because DIRTY is an adjective. To be a direct object (i.e. to be something he likes) it needs to be a noun. So, some words that would work would be: He doesn't like . . . dirt, dirtiness, uncleanliness, messes, untidiness, etc.

It would be better written.......... "He doesn't like dirt..." And the alternative to the second sentence would be "I mean he wants everything clean" or "he wants everything kept clean"
