I don't think there's a good way to do that since yt-dlp approaches things differently. It's using the "PC" endpoint, which is less strict with VPN/proxies and doesn't require any modification to the URLs, so it can just iterate through all the manifests from all hosts and simply skip the ones that fail. The downside is that this endpoint maxes out at 720p.
The Devine/Unshackle service is written to get the best available streams (up to 2160p), which comes at a cost of them being more restricted overall. And you really don't want to make a script worse by falling back to a lower quality when the intention is to get the best - especially when the limiting factor is the user's own setup. -

Thank you for Freevine and the services. Thank you for the information about PC Endpoint being less strict for VPN. I am usually happy with 720p and less. Maybe someone one day will make a iP service for the PC endpoint and say this is for 720p and less that will be more successful for those who have VPN issues.

Can someone provide me a working service which I can use to build my own? Stuggling hard to understand how to.

Take a look at the code for the downloader. devine/core/service.py lists the abstract methods that your service code MUST implement. All the instructions are in the source code. Following an existing service wont be too much help as each implementation is different.
A forum search will reveal services I have posted here for devine and unshackle if that's what you want.
Your service class. say, class BigTv(Service): needs to inherit the Service class in devine/unshackle and implement all the abstract methods and over-ride some/all of the others.
service.py code for devine - unshackle will be a close match.
