[TYPO3] Is it possible? Could a BE form be defined according to a record value.

I am trying, but it does not seem to be enough.
First, I would like to have something like a if ... else clause:
if  "displayCond"=> "FIELD:field:=:A" then config = blabla
else "displayCond"=> "FIELD:field:!=:A" then config = clacla
Second, I need to check a value from a different table.

Neither seem to be possible, are they?
I appreciate any further hint and advise.
my best wishes
