Is there any way to disable the focus ring around the ShadCN dropdown menu?

I’m trying to configure the ModeToggle button that is in the ShadCN docs for light/dark mode theming and I’m bothered by the focus ring that appears next to the dropdown menu.

I looked into the code for the dropdown menu and tried to disable things such as bg:accent or bg:text-accent, etc. But I didn’t get any change. Would appreciate some help, thanks!
