Never used Valheim Plus, but if you download the Official Configuration mod, then hitting F1 in game will allow you to change all the settings in your mods. Or you can use the Configuration editor in the Mod Manager.

Unfortunately, Valheim Plus doesn't show up in the configuration manager. You need to either change the settings for it by editing the .cfg file in a text editor, or install the Valheim Plus Manager[www.nexusmods.com] application to do it. In both cases, you have to modify/edit the configuration outside of the game.
