Redirect to specific Isp in multi isp setup

Hello there

I have a hAP ac2, routerOS v7.8.

As an ISPs I have a local provider (fiber optic + mediaconverter) on port #1 and a starlink ( set starlink router in bypass mode + starlink ethernet adapter) on port #2.

All other ports - LAN, cables go to another routers accross the home.

Using a Google and YouTube I have configured firewall mangle rules, so both ISPs work in load balancing mode using per connection classifier (PCC) .

The problem is that some websites (mostly streaming services with a subscription) are displaying error, when the connection is made using starlink, but work fine with my local isp.

So the question is - how can I adjust my firewall rules so specific sites will use only isp1?
