Can I use a screen protector on my MacBook Pro M2 Pro?

You "can" but it's not advisable. It adds thickness to the display which may eventually cause problems. When the laptop is closed, there is only a tiny space between the display panel & the keys on the keyboard. A screen protector takes up most and maybe all or more of that space, so the display ends up in contact with the keys.
