2 Pole GFCI on MWBC

Older home, ungrounded 2 wire running everywhere. I have one MWBC running to the downstairs kitchen and living room. I’ve put single pole GFCI breakers on the rest of the standard circuits. Is there any reason I can’t put a 2 pole GFCI breaker on the MWBC. We replaced the panel and it’s an Eaton CH plug on neutral panel. I redeviced the whole house and I didn’t pay attention if there were any splits in any of the boxes and there are no junction boxes throughout the house. I’d like to avoid having to search for the split point if at all possible.

I’m sorry I can’t provide details but I’ve read in other forums how certain brands of DP GFCI breakers wouldn’t be compatible or not

General questions usually get general answers. Almost nothing is 100%.
Do you have a specific application issue or product you are working with?
