Does a Pokemon gain EVs when participating in a Max Raid Battle?

I do know that Pokemon do not gain experience after a Max Raid Battle ends; however, I'm asking this to be sure, since I am raising some Pokemon and want to use them in the process. When a Max Raid Battle is won, do participating Pokemon receive Effort Values based off of the species battled, as in wild battles?

Solution 1:

No, Max Raid battles do not provide EVs. This is confirmed here, here, and here.

To test this, one of the sources took a Ferrothorn that had no EVs in any stat into a raid battle. After the boss was defeated, they used berries that reduces EVs on the Ferrothorn for each stat. Each berry gave the message indicating no stats were lost
