I want to debug with the monitor, plug the DP cable to AMD card. After doing the power cycle, it entered to the BIOS, observe through the screen that the kernel has been started, but it immediately turned into a black screen. Fortunately, it can ssh-able, it can work normally by using the onboard graphic card. After checking, AMD graphic card is broken after upgrading to 5.15.0-89-generic, it still have same issue in "5.15.0-91-generic" kernel version, but everything is good in the "5.15.0-88-generic" kernel version.
