Hi
There are some work arounds but I’m not sure about the jailbreaking side of things
There is a method of having someone go onto a server and disables something on apples side of things but there aren’t many people that will do it legitimately and you could scammed by them so I don’t really recommend them
Apart from that there aren’t any options that would be worth it for the price
You could go into the board repair side if things and replace the SoC and some other things but at that point you are risking breaking the whole device and if you haven’t done the micro soldering side of things it isn’t recommended until you have enough experience
Here is a video on having it done though

This isn’t video isn’t for a iPad but it’s a similar process on the board side of things
If I were you I would sell the iPads off on eBay for parts as people would probably pay a little extra knowing that they are fully working and just iCloud locked as they could get lots of valuable parts like the logic-board and housings out of them
But that’s your decision and it’s up to you:-)
Hopefully this helps
Any questions please ask
Thanks:-)
