Overclock - Pi Top OS

just bought a Pi Top 4, was trying to overclock it using
sudo nano /boot/config.txt

but the config.txt seems different. i am not able to spot
#uncomment to overclock the arm. 700 MHz is the default. #arm_freq=800

any advise on this? or i cant overclock with pitop os

thanks

config-txt edit got it, it is actually very simple, just type in

sudo nano /boot/config.txt

and add

hashtag Overclock Instructions
arm_freq=1900
over_voltage=4

(please see print screen for actual input)

then click ctrl x, you will be prompted to save your work.

to check your overclock speed, key in lscpu

i have overclock it to 1900MhzCPU @1900
