There are such services available where you can use your NFT's as collateral, Why not try seek out those platforms which is more suited to what your looking for in your circumstance.
By the way @AussieMat, speaking of borrowing using your NFTs, i recently discovered this service.I am not sure if they really work since I haven't tested it out, but it might be worth exploring in case you haven't known it before.
Just make sure you DYOR as I haven't used it before, so positive results are not guaranteed.
