These apps can be blocked using Layer 7 firewall rules and/or Content Filtering, depending on your MX model and license.

Add rules under Layer 7 > Block Web Traffic by Hostname

You can often block an app by creating Layer 3 firewall rules that block all access to the DNS domains it uses.

I asked Gemini:
What DNS domains does zalo web, zalo app and viber app use? I want to block them on a firewall.

Here is the answer:

Note the "Firewall Blocking Tips" section at the bottom.  Except I would just block all IP traffic.
