Is there a way within in AttributeValidator Parameters -> Validation Rule -> Rule Configuration -> NOT EQUAL a value?

Could you use a 0 width negative lookahead in the regex?
Something like PROJECT_ID Contains Regex ^(?!@Value(_projectid))
It won't work if _projectid is found entirely within PROJECT_ID.
ex. projectid = 123 and PROJECT_ID= 1234
I think this will work if you want to fail only exact matches, not contains as well
^(@Value(_projectid).+|(?!@Value(_projectid)).*)$
Alternatively, could you replicate the logic in a tester?
