Would also like to know if this is possible.

Hello,

did you unckeck the Inspect in your Elvui Skin options? There is a seperate option beside turning of the player character frame skin. 

Title basically. Can't seem to turn off the ElvUI transparent skin for the Inspect Player Frame if I want to use the armory mode for Shadow and Light.

The ElvUI skin for player character frame with armory mode stays off but not inspect other players.

[HELP] How to turn off elvUI skin for inspect character window with armory mode on in elvUI Shadow & Light?
