Unround iOS simulator corners in Big Sur?

In macOS Big Sur, is there a way to remove the rounded corners from the iOS Simulator windows? I'm not looking to change this setting system-wide, just for the simulator.

Why? For older simulators like iPhone 8 and older iPads, the rounded corners in the non-bezel windows clip part of what the end user would see. It's small, but it matters in my use case.

AFAIK, there is no way to customize simulator. Does this cause you problem with simulator screen capture (cmd-S) ? Only thing is to send a bug report for an improvement request.
