Capture HTTPS traffic for Roku/Set-top box devices over Transparent mode

I have setup Mitm proxy in transparent mode and able to monitor HTTP traffic of Roku(Set-top Box) but would not be able to sniff HTTPS traffic as there is no way to install mitm’s certificate on Roku device using URL.

Is there any way to sniff HTTPS traffic for such deices?

Also, Is there any way through which i can restrict only either few domains or client IP addresses to sniff HTTPS traffic and not for all domains/IP addresses using mitmproxy/mitmdump?
