On the CP/M cards I've used (the Softcard and the Appli-Card) it was
automatic: I just inserted my Videx card in slot 3, and CP/M booted
up automatically in 80-column mode.  Quite sensible, since a lot of
CP/M software assumes 80 column.  Once I tried, in vain, to configure
WordStar for 40 columns: it didn't work, since WordStar required a
minimum of 64 columns....

It's definitely possible, but will require that you dig a lot "under
the hood" yourself, and acquaint yourself with how the SoftCard
BIOS works (both the Z80 and the 6502 parts).  And if course you
must also know how to access your UniDisk 3.5" from 6502 assembly
language.  Good luck!  (no, I can't help you since I don't know
how the UniDisk 3.5" works)
