I have two SSID's at home. I find that if I have a weak wifi signal my Honor View 20 reverts to mobile data. This can be manually disabled by clicking the blue "undo" arrow in wifi networks.
I would ideally like to disable this via a setting (as can be done with Apple), particularly as my phone seems to do this when theres a perfectly good alternative wifi SSID available.
Welcome to Android Central! I don't know if there's a way to do it from a setting, but one workaround would be to toggle your mobile data off yourself when you're at home.
Also, consider getting a mesh wi-fi network solution for home (like Google Wi-fi or Orbi). I used to futz around with two different SSIDs for two different access points at home, which was a pain. Mesh works so much better!
Using the Settings app, In the "developer" settings, check the "networking" section to see if any of those options might help, like "aggressive handoff".
