MIL won’t stop talking about things I don’t care about

I have a not so great relationship with my MIL. She never has been extremely welcoming to me and when she is it feels very performative. She has a tendency to never ask about myself, my husband, or our baby. Instead she fills all silence with topics that I do not care about such as tv shows and her other grandchild. It’s always a story about how great she is or how she babysat her which is either to show me that she’s a great grandma or just because she truly thinks I’d rather hear about the other child than have her get to know my child. The only other topic is her giving “advice” constantly about how we do things in the small amount of time we spend with her which is also annoying AF since we’re FTP. I am a conflict avoider and feel like even if I say something she would never take it well. Do I address this so I don’t continue to resent her or just suck it up?
