DNS traffic can leak outside the VPN tunnel on Android

This issue(Google Issue Tracker) remains not fixed till now but configuring private DNS prevents the leak partially[1]. There’s a mitigation via adb for another widely known bug where any app on recent Android versions can leak certain traffic[2][3], is there a similar fix through ADB possible for this bug too?
