Do splash guards affect the EV range?

[EquinoxDriverR2020]

Hello! My brother just bought a 1LT EV. It has to come with splash guards, but he asked the dealer not to install them just yet. We heard mixed things about how splash guards might affect EV range (mostly from Tesla owners, that's true). He would like to leave them off to maximize efficiency. Do you think is this a good move? Could they really impact a range that significant?

Splash guards may minimally impact range but protect against debris.

@Tridentlord is right. But if you still want to go with this decision, just put some rust oleum primer in the holes. My concern would be the screw holes going rust.
