How to enter TTY mode in CoreELEC

I am using a Dangbei B3Pro box(S922X), but it is temporarily unable to use the network. I need to enter TTY mode to change the driver. Since the driver cannot be used, I cannot enter the SSH terminal. I use Microsoft Copilot to search and press ESC when prompted, but I cannot enter the GRUB menu. How to enter TTY mode?

CoreELEC Version:9.2.5
