There is a hole between Windows partitions and Windows recovery partitions:

parted /dev/nvme0n1
print free
Number  Start   End     Size    File system  Name                          Flags
        17.4kB  1049kB  1031kB  Free Space
 1      1049kB  106MB   105MB   fat32        EFI system partition          boot, esp, no_automount
 2      106MB   123MB   16.8MB               Microsoft reserved partition  msftres, no_automount
 3      123MB   60.3GB  60.2GB  ntfs         Basic data partition          msftdata
        60.3GB  511GB   451GB   Free Space
 4      511GB   512GB   944MB   ntfs         Basic data partition          hidden, diag, no_automount
        512GB   512GB   335kB   Free Space

So create 16GB swap at end and BTRFS for root part.

parted /dev/nvme0n1
 
mkpart swap sw 495G 511G
mkpart root btrfs 60.3GB  495GB

mkfs.btrfs /dev/nvme0n1p6
mkdir /target
mount /dev/nvme0n1p6 /target
cd /target
btrfs sub create @rootfs

sudo apt install netcat-openbsd pv zstd

Sender:

btrfs send | zstd --fast -T0 | pv | nc -w 2 -N <remote_ip> 44444

Receiver:

nc -vl 44444 | zstd -d | pv | btrfs receive /target
