If you're seeing that message from the system, then it's likely a firmware-level modification that you can't change. If you can't do it in the menu mustang7757 described, then you're probably stuck. The only solution I can think of would be to flash the device with a custom ROM, but (a) that's not something I would recommend if you don't have any experience with it, and (b) it's unlikely that anyone has designed a custom ROM for that device anyway, considering how uncommon it is.
I also wonder if this is Android 11 Go. Android Go is a more lightweight version of Android used on more underpowered devices, and it doesn't have as many features:
