I would like to consult some questions about UEFI optimization。

Thank you very much for your reply. I followed the instructions from “How can I remove text printing from the UEFI Logo interface?” to delete efi-stub.c, fdt.c, and efi-stub-helper.c, but I got an error when compiling the kernel.
I also modified the L4TLauncher.c file. However, the UEFI logo interface still has text printed.
