How to lower or change my TTY (1-6) resolution?

System: Linux Mint 20.1 64-bit, kernel 5.4.0-74-generic, Nvidia proprietary display driver.

Here is

log direct view link after boot with these changes done:

/etc/default/grub
:

GRUB_GFXMODE=1024x768
GRUB_GFXPAYLOAD=1024x768
GRUB_GFXPAYLOAD_LINUX=1024x768

/etc/grub.d/00_header
:

#if [ "x{GRUB_GFXMODE}" = "x" ] ; then GRUB_GFXMODE=auto ; fi if [ "x{GRUB_GFXMODE}" = "x" ] ; then GRUB_GFXMODE=1024x768 ; fi
if [ "x{GRUB_GFXPAYLOAD}" = "x" ] ; then GRUB_GFXPAYLOAD=1024x768 ; fi ... set gfxmode={GRUB_GFXMODE}
set gfxpayload=${GRUB_GFXPAYLOAD}

On UEFI, calling

videoinfo
for the list of supported resolutions:

GRUB videoinfo


I feel desperate already as nothing I tried changes my laptop’s native resolution of 3840×2160.
