I had try to using nrfutil with --debug-mode for bootloader

Is it option support for package Application only?

Hi Joe Yeh,
Have you defined NRF_DFU_DEBUG_VERSION or NRF_DFU_DEBUG in the sdk_config of the bootloader. If you don't define that using --debug-mode wouldn't work.
From what I can see in the code when you use NRF_DFU_DEBUG, fw_version_ok() will be skipped and it's where the bootloader version is checked.

If you already define NRF_DFU_DEBUG, you may want to debug and check what caused the invalid parameter in the bootloader.
@Hung Thanks your feedback.
So.. that "--debug-mode" only work for bootloader example with "_debug"
Then using nrfutil with "--debug-mode" can work for skip version check
