The following applies to Microsoft CSP and Partner Centers. If you don’t have enabled auto-extend enabled on your customer GDAP-relationships, you can use this script to modify the property called “autoExtendDuration”, to enable it.
You can find more under Microsoft GDAP FAQ
Example:
Install-Module Microsoft.Graph -Scope CurrentUser -Repository PSGallery -Force
Normally, we’d use Set-MgTenantRelationshipDelegatedAdminRelationship to set the autoExtendDuration property, but this commandlet is currently missing implementation to handle a required If-Match in the request header. See Github issue.
The workaround is to use Invoke-MgGraphRequest as demonstrated with this script.

$gdap = Get-MgTenantRelationshipDelegatedAdminRelationship -All | Where-Object {($_.status -eq "created" -or $_.status -eq "active") -and $_.EndDateTime -lt $(get-date).AddDays(60) -and ($_.AdditionalProperties.autoExtendDuration -eq "PT0S" -or $_.AutoExtendDuration -eq "00:00:00")}
$total = $gdap.count
$count = 0
