Gender Neutral Parent Name

I 29 (MTF) have a daughter. I’m to the point in my transition where no one bats an eye that I was wearing a mask. I don’t get misgendered only by bigot family and co workers… When my daughter and I are out she calls me dad. I know I’ll always be that. But with today’s society it’s not safe. I talk to my Ex about this a couple months ago and it didn’t go well with them. They hate what I’m doing and don’t want our daughter to say anything but dad. My daughter calling me mom is off the table as I’m not going to risk loosing custody. Is there any good gender neutral names for parents?
