How can I get my grandparents support?

I’m not a Christian so im not sure if im allowed to post this but oh well. Recently, I’ve started my transition from ftm, and it’s been really hard. My parents aren’t the most hardcore christians but my grandparents are. Family gatherings have been really awkward and they’re all just either ignoring me or blatantly being rude. Is there anything I can do to make them love me again? I know who I am and nothing they say is going to change me, but I miss their love
