Please some way to hide bios

I ended up adding my dad to discord (ik mistake right there) just because I hate using normal phone texting, and he actually got really good at using the site. Only problem is that he pays close attention to bios, even asking why a heart is a certain color. I used to put personal friend group stuff in there or medical/system stuff but I can't anymore because he'll want to question me. (Or exorcize me again.) Can there please be a way to mark someone as a parent or have some ways to hide your bio from certain people? I don't want to remove him, it would just make him sad but I feel like I have less freedom now.
