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?

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
