Thanks for your getting support on Q&A forum.
To avoid misunderstanding and get the better support, please help to describe your demands in detail. What is the meaning of Is it possible to delay the installation of updates when they are deployed with WSUS ?
As far as I know, we could configure the Configure Automatic Updates Group Policy and select the option 4 - Auto download and schedule the install and specify the schedule to install the updates.
Here is a related link for your reference:

In my opinion, we could apply the Configure Automatic Updates for the clients and the clients will try to install the approved updates as schedule.
Hope the above will be helpful.
