Hi Isaias,
Regarding the snipping tool shortcut, there's no built-in way to change it.
As for remapping the snipping tool, you need to download PowerToys by MS.

To enable the keyboard manager and remap shortcuts, first activate the keyboard manager. Then, proceed to remap the shortcuts by typing in the current shortcut followed by the new desired shortcut.
I'll send you a screenshot of how it should look like
Regards,
Levi
