LockState NoAccess for all

[F0RCE]

Is it possible to put all site collections in LockState NoAccess?

If yes could you please provide a PowerShell code or a GUI place where I can do that?

I want to kill my Sharepoint temporarily - taking away licenses didn't work, and when I took away site collection rights it helped, but I have 1000 users I do not want to change permissions manually.

Please help me. Thank you!

#State has one of the following values:

#Unlock to unlock the site collection and make it available to users.
#NoAdditions to prevent users from adding new content to the site collection. Updates and deletions are still allowed.
#ReadOnly to prevent users from adding, updating, or deleting content.
#NoAccess to prevent users from accessing the site collection and its content. Users who attempt to access the site receive an error
