GFCI multi-wire branch circuits

Hello All! I'm new to this forum, as I am sort of new to DIY stuff. I've owned a fairly old house (110 y/o) for going on 4 years now, and I'm getting more and more into projects. One area I know very little about (but have the most respect for) is Electricity. As a firefighter I know what it can do, and also as a firefighter I can't really afford to pay professionals to work on it all the time. So here's my question.... I have a GE Load Center with several breakers having what I believe is called multi-wire branch circuits (one 3 wire cable feeding two breakers?). My question is, can I replace just one of the two breakers with a GFCI or Afci/Gfci Dual Function Circuit Breaker? :help: Thanks in advance for your assistance! Cheers!
