Can't get past "no mouse" screen in macOS Recovery mode

Hi there,

this may be a strange problem to have, but since the latest macOS Big Sur (11.3) update, I can't get rid of the "no mouse" screen in the macOS Recovery Mode (using a M1 Mac mini).

Unfortunately, it's not easily possible to connect a mouse to the device, since I'm using it remotely using an external KVM device. This means that an external mouse device is connected, which sends absolute positions instead of relative positions (think digital drawing pad).

While the mouse does work in recovery mode (I am able to move it around and click the restart option in the menu), it seems like the OS is not recognizing the device as a mouse and therefore not allowing me to bypass the screen. I have attached a screenshot showing the mouse cursor on the screen:

In earlier versions, clicking the mouse was enough to get rid of this screen and continue using it, but this seems to no longer work.

Is there any way to bypass or avoid this screen without attaching an external mouse to the device?

Thank you for your help!
