Disable boundary relocation pop-up in Stationary Mode (Meta Quest)

When using the Stationary Boundary on Meta Quest, every time I step outside the boundary, a message pops up asking:

“Do you want to move the boundary here?”

I’d like to keep the stationary boundary active, but remove or disable that pop-up question.

This is for an art installation, where I need to freely move in and out of the boundary using passthrough without interruptions or warnings.

Does anyone know how to do that — maybe through developer settings, ADB commands, or the Meta Developer Hub?
