Method to block calls on dual SIM and block notifications from some apps (scheduled)

I recently got a Motorola G5S Smartphone with Android 7.1.1 with Dual SIM. One SIM is work-related, the other private. Also, every App on my phone is either work-related or private. I'm searching for an app (or integrated function) which can do the following: - block all calls & messages coming into the work-SIM at night & on weekends - block notifications of the work-related apps at night & on weekends The tricky thing here is that I do want to use the mobile data from the work-SIM, so disabling it completely is not an option. I checked out Tasker but the description doesn't say anything about blocking calls coming in to one of the numbers/SIMs. On the other hand, the "Do not disturb"-option also cannot to block only calls to one SIM (at least on my phone ). Is there any other app or even built-in feature that I'm missing? Rooting the device would not be a problem, I guess.
