The Huawei Mate 40 Pro earns a 4 out of 10 on our repairability scale (10 is the easiest to repair):

Huawei uses standard Phillips screws throughout the phone.

All major components are modular enough to be accessed/replaced independently... if not easily.

Pull tabs make the battery removal easier, but you'll have to work your way through plenty of cables and covers first.

Glass on front and back doubles the likelihood of drop damage.

The display adhesive is insanely strong.

The display can't be replaced without removing the battery, and the under-display fingerprint reader can't be replaced without removing the display.
