PowerShell to Set Header layout, Site Logo and Background:
Lets change the SharePoint Online header layout, header background color and header logo using PowerShell.

#Set Variables
$SiteURL = "https://crescent.sharepoint.com/sites/credit"
$LogoURL= "https://crescent.sharepoint.com/sites/credit/SiteAssets/logo.jpg"
  
#Connect to PNP Online
Connect-PnPOnline -Url $SiteURL -UseWebLogin
 
#Get the Web
$Web = Get-PnPWeb

#Set Header Options
$Web.HeaderLayout = "Standard"   # Standard, Compact
$Web.HeaderEmphasis = "None"  # None, Neutral, Soft, Strong
$Web.SiteLogoUrl = $LogoURL
$Web.Update()
Invoke-PnPQuery

Please note, on group connected modern sites, SharePoint gets the logo from the group! So we got to set the logo of the Office 365 group.
