REM Save this file i.e. to your Desktop. Whenever you want to disable Vanguard,
REM simply run it as Administrator.
REM If you run VALORANT while VGK is deactivated it will re-install it and ask you to reboot.

REM You can adjust the path to Vanguard here:
set VGK_PATH="C:\Program Files\Riot Vanguard\vgk.sys"


REM Check whether VGK.SYS exists
if exist %VGK_PATH% (
    goto deactivate
) else (
    goto activate
)

:activate
SET /P AREYOUSURE=Enable Vanguard (Y/N)?

move %VGK_PATH%.deactivated %VGK_PATH%

goto SOFTEND

:deactivate
SET /P AREYOUSURE=Disable Vanguard (Y/N)?
IF /I "%AREYOUSURE%" NEQ "Y" GOTO END

Just wanted to share my solution. It disables both services and removes Vanguard from auto start.
Run as admin.

enable:

sc config vgk start=system
sc config vgc start=demand
powershell -Command "Set-ItemProperty -Path HKLM:\Software\Microsoft\Windows\CurrentVersion\Explorer\StartupApproved\Run -Name 'Riot Vanguard' -Value ([byte[]](0x02,00,00,00,00,00,00,00,00,00,00,00))

disable:

sc config vgc start=disabled
sc config vgk start=disabled
powershell -Command "Set-ItemProperty -Path HKLM:\Software\Microsoft\Windows\CurrentVersion\Explorer\StartupApproved\Run -Name 'Riot Vanguard'  -Value ([byte[]](0x33,0x32,0xFF))"
