my suggestion is to create an empty partition (unformatted) on the free space. The only thing i see is that the partition numbering is not alligned ..

├─nvme0n1p1 part   260M gpt    vfat
├─nvme0n1p2 part    16M gpt    
├─nvme0n1p3 part   1.3T gpt    ntfs
└─nvme0n1p4 part   871M gpt    ntfs

the empty space would be nvme0n1p4 but thats already taken by the last ntfs partition after the free space.. generally should not be an issue and would get sorted with partion creation..

But i am sure it will get resolved with creating empty unformatted partition before starting installer, reboot into installer iso and use this real partition to replace with BTRFS.. It will select nvme0n1p1 part 260M gpt vfat to be used for ESP (boot efi partition) you can also select to create a new one.. but should work with default.

   system is EFI and new EFI system partition has been found

shows no issue booting in efi mode..

And thanks for the useful report!
