The page for the UI mod mentions that it includes these settings related to enemies:

Show enemy level: Text, Stars, Both
Show enemy HP amount (includes bosses)
Aware / Angry status colored on enemy name
Custom render distance

I have not installed the mod myself or used Valheims mod loader, but I imagine that there is an opportunity to select/deselect these options when performing a completely fresh install of the mod.
And the page for the mod also says that when you do a manual install it will automatically generate a config file anyway at BepinEx/Config, which I expect gets placed in the games install directory. That looks like it could be an alternative way of manually changing the mod settings via notepad or another text processing app.

I would have also said to make sure that your load order is in check but I don't reckon that would be the problem with those other mods disabled. Generally if you don't want parts of one mod to be overwritten by overlapping contents of another mod, you put it later in the load order.
