Install dedicated AMD drivers for laptop S540

Problems

Laptop S540 has dedicated AMD 4800u integrated graphics, at first, I downloaded the driver from the lenovo official site but recently I want to upgrade the graphics card following AMD's official driver, which is more update, but everytime after the upgrade, Windows 11 automatically revert the old version driver making the new AMD driver being warned with not compatiable.

Solutions

The whole concept is to prevent Windows from checking and changing the driver automatically.

1. Navigate to Device Properties and find the AMD graphics hardware, click `XXX Grahpics Properties`  

At the same time, open Local Group Policy Editor and navigate to Administrative Templates > System > Device Installation > Device Installation Restrictions, find and edit the below entry

Enable the settings above with the entry values shown in Device Properties.

Apply the settings for each driver upgrade, disable the settings next time when a new driver update is needed

[System] Remove Backup Volume from Laptop

Background
Bought a new laptop, but the partition is being chopped into different pieces, 512GB of SSD spaces is being chopped into half of system and half of data, and some are being occupied by Acer backup partition which is not what I wanted.


Solution
Following this guideline https://macrorit.com/wipe-hard-drive/delete-oem-partition.html, I first list current volumes and remove the 1 using command line interface. Restart the laptop, and the backup partition is backed again!
