One easy potential repair is adding a sealant to your radiator. It doesn’t work on all head gasket issues, but it does work on some (at least for awhile) and could extend the useful life by a bit.
This stuff sealed a radiator (non head-gasket) leak for me and there are reviews and videos of it fixing leaks in the head-gasket as well.
That seems like a better option than taking apart a dashboard or throwing down a grand for this.
Have you ever used any of those additives that seal leaks on their own? I'm hoping to just have a fix hold me over until after winter at the latest.

Maybe a sealant can help you for a while, but given the amount you're losing I bet it's a big leak.
