Removing lines of staves

Hey y’all,
I’ve been looking through a bunch of these posts and I haven’t found anything explaining what I’m trying to do, so I though I’d ask here. I’m trying to create a reference electronics part for a piece for classical guitar and electronics playback by using graphic frames to put the graphic notation below the guitar part. Right now I’m just using a percussion staff with the name changed and it looks alright except for the fact that I can’t seem to remove the line that goes all the way through the staff. Is there any way to do this? Maybe a totally different method that I didn’t think of?
Any help would be so appreciated, thank you

Horizontal or vertical line?
Maybe a screen shot of the line in question.

Everything ideally, although the barlines get covered up so they’re not really a concern. I also would love to not have a clef there but that also seems like it’s a difficult process…

Given that you’re doing ‘graphical’ notation, maybe output a basic score from Dorico as a PDF, and delete the staff lines in a vector drawing package, like Affinity Designer, where you can also add graphical elements easily.
