HISTORY_IGNORE just stops things being written to history files;
I don't think that's quite you want.  If it was, it's a single pattern,
so you should be able to do

HISTORY_IGNORE="(rm|ls) *"

You can do this, though:

zshaddhistory() { [[ $1 = (ls|rm)\ * ]] && return 1; }

and indeed there's no reason I can think of why you couldn't simply
define

zshaddhistory() { [[ $1 = ${~HISTORY_IGNORE} ]] && return 1; }
