Purchased iCloud locked MacBook Pro- ghosted by seller

Hello all

I purchased a macbook pro model A1706 and found out it was icloud locked. What can I do with it now? I was thinking maybe I could find the same model cheaply but with a damaged screen and swap it to make the most out of my loss. I'm not savvy with electronics- but I have replaced the displays of a few Samsung phones and an iPad.

Would it be better to just try to sell it as is to recoup my losses? And if so how much should I ask for?

Any advice is welcomed, as this situation has kind of derailed me and now has turned into something way more complicated than I intended.
