Onedrive regional settings

Hi @Anonymous ,

Welcome to Q&A Forum!

Please run the below PowerShell script as an admin on the SharePoint Online Management Shell:

#Set Config Variables  
$SiteURL = "https://domian-my.sharepoint.com/personal/username_domain_onmicrosoft_com/"  
$TimezoneName = "(UTC-08:00) Pacific Time (US and Canada)"  
#English  en-US   1033  
$LocaleId = "1033"  

#Connect to SharePoint Online with PnP PowerShell  
#Enter the user account and password corresponding to the Onedrive page  
Connect-PnPOnline $SiteURL -Credentials (Get-Credential)  
   
#Get the Web  
$web = Get-PnPWeb -Includes RegionalSettings.TimeZones  
   
#Get the time zone  
$Timezone  = $Web.RegionalSettings.TimeZones | Where {$_.Description -eq $TimezoneName}  
   
If($Timezone -ne $Null)  
{  
    #Update time zone of the site  
    $Web.RegionalSettings.TimeZone = $Timezone  
    $Web.RegionalSettings.LocaleId = $LocaleId  
    $Web.Update()  
    Invoke-PnPQuery  
    Write-host "Timezone Updated Successfully!" -ForegroundColor Green  
}  
else  
{  
    Write-host "Timezone $TimezoneName not found!" -ForegroundColor Yellow  
}  

Here is my test:
