Hello @harshdamaniahd

I tried with App only approach and got the same error.

Required permissions for this command is

Type	API/ Permission Name	Admin consent required
Delegated	AllSites.FullControl	yes

With below approach using parameters ClientId, DeviceLogin, LaunchBrowser

Connect-PnPOnline -ClientId xxxxxxxx-0000-4xxxx-xxxx-xxxxxxxxxxx -Url "https://xxxx.sharepoint.com/sites/xxxx" -DeviceLogin -LaunchBrowser -Tenant xxxxx

I was able to execute this succesfully

PS C:\Research\PnPCommunity\powershell> Set-PnPSiteVersionPolicy -EnableAutoExpirationVersionTrim $false -MajorVersions 100 -MajorWithMinorVersions 10 -ExpireVersionsAfterDays 200
WARNING: The setting for new libraries takes effect immediately. Please run Get-PnPSiteVersionPolicy to display the newly set values.
WARNING: The setting for existing libraries takes at least 24 hours to take effect. Please run Get-PnPSiteVersionPolicyStatus to check the status.
WARNING: The setting for existing libraries does not trim existing versions.
PS C:\Research\PnPCommunity\powershell>

@gautamdsheth I will add required permissions for these two commandlets in the PR #4488

Thanks,
Nish
