I use flameshot, and I don't want the built-in tool.
I disabled shortcuts in gnome settings, but with no effect
I tried to:
>>:~$ sudo apt remove gnome-screenshot

How to get rid of the built-in screenshot tool?
The built-in screenshot tool is, well… built-in! So you can't easily get rid of it, not without rebuilding GNOME.
But you can get it out of your way! This is done by going to Settings > Keyboard > Keyboard Shortcuts, look for "screenshot" there and remove every shortcuts for the built-in screenshot tool.
You can also add a custom shortcut for Flameshot there. Go to Settings > Keyboard > Keyboard Shortcuts > Custom Shortcuts section, click on the plus (+) sign, type in a name for your shortcut (like "Run Flameshot"), then a command (like "flameshot gui -c -g") and finally choose your favourite keyboard shortcut for it. I chose Super+PrtScr, but you may just use strait PrtScr, if you actually disassociated it from the built-in screenshot tool before.
I just upgraded to Ubuntu 22 today, and I was struggling with the native screenshot intercepting every call to other utilities (e.g. Flameshot). Turning off Wayland made it stop.
From here:
sudo vi /etc/gdm3/custom.conf
Uncomment:
WaylandEnable=false
Reboot.
