None of my Windows 2022 Server instances will automatically TRIM my SSD volumes on a schedule, so I wrote this script to run as a scheduled task.

Run-Trim.ps1

# Simplified version runs defrag command against all drive letters with only the TRIM flag. Original version 
# did not run against my Storage Spaces RAID volumes since it couldn't convert a member Physical Disk to a
# drive letter but this version does. Drive letters that Windows doesn't recognize as SSD will be skipped.

$( Get-Volume | Where-Object { [string] $_.DriveLetter -ne '' } | ForEach-Object { "$($_.DriveLetter):" } ) -join ' ' | ForEach-Object {
    & defrag $($_ -split ' ') /Retrim /MultiThread
}

In retrospect, possibly just running defrag.exe /Retrim /AllVolumes /MultiThread would work.
