This seems like a pretty niche scenario, maybe we should just keep a
global for the max ASID?

Otherwise we need a code to change the ASID, even for non-SVA domains,
when the domain is installed in different devices if the current ASID
is over the instance max..

Ideally domain ASID would be selected at domain allocation time.
