Uninstalling windows defender

there are two default actions available in my bigfix management server

1- Windows defender Service Stop.
2- windows defender unistallation.

1- in service stop action it was showing that almost 2000 clients were relevant to this action as these 2000 client were having widows defender in it.

2- but it is showing no relevance when it comes to uninstallation action task even though in a graph of BigFix console it is still showing 2000 Windows defender clients.

Can anyone suggest me that what should I do , as i need to uninstall defender AV from my machines.

Regards
