No because at the start of a turn mega evolution goes first. Even before priority moves.

Answer 1

Mega Evolution always occurs before any moves are executed, even Pursuit.

Mega Evolution and Dynamaxing generally occur at the beginning of a turn but after any switching has occurred; however, if a Pokémon is Mega Evolving or rotating in and then using Pursuit on a Pokémon that is switching out, the Mega Evolution or rotation always happens before the Pokémon uses Pursuit (and therefore before the other Pokémon's switch).
