Is it possible for ipKVM to set an unsupported resolution?

Question

System administration

There is a mac mini. We launch via kn1000a (ipKVM), decrypt, etc.
After starting, we connect remotely, but the screen has a maximum resolution of 1920 * 1080 pixels. Need 4K. How can I switch after startup? ipKVM itself only supports 1920*1080, but there must be a way to pass an unsupported resolution to it in order to further broadcast it to anydesk, VNC, etc.?
Maybe fix EDID somewhere, something like that? In the menu and a simple program like switchresX - does not come out.
