    I believe you are referring to the kernel command line arguments? is so, you can use UEFI to change these options. During the boot sequence, interrupt the automatic kernel boot UEFI performs by pressing a key. Navigate to '[3] Boot Manager' then to '[2] Update Boot Device Entry'. One of the entries is "Arguments to pass to the binary: ". For example:

    The default boot selection will start in  10 seconds

    [1] Linux from NOR Flash

    [2] Shell

    [3] Boot Manager

    Start: 3

    [1] Add Boot Device Entry

    [2] Update Boot Device Entry

    [3] Remove Boot Device Entry

    [4] Update FDT path

    [5] Return to main menu

    Choice: 2

    [1] Linux from NOR Flash

    Update entry: 1

    File path of the EFI Application or the kernel: Image

    Has FDT support? [y/n] y

    Add an initrd: [y/n] y

    File path of the initrd:

    Arguments to pass to the binary: console=ttyAMA0,115200 earlyprintk=pl011,0x7ff80000 root=/dev/sda1 rootwait verbose debug
