Sure is ;-) Disclaimer: not to deeply tested yet though.
https://git.proxmox.com/?p=pve-qemu.git;a=blob;f=debian/patches/pve/0044-PVE-Add-PBS-block-driver-to-map-backup-archives-into.patch;h=855cc2207aea67fab330f2a205ddb92322bd4fb0;hb=3499c5b45a30a3489ca0d688d2d391fdfe899861#l116

Short procedure example to use it could look somewhat like:

# modprobe nbd

# export PBS_PASSWORD='12345supersecure!!!'
# export PBS_FINGERPRINT=00:b4:b5:50...
(above could be also passed directly as option, but well)

# proxmox-backup-client list --repository root at pam@192.168.1.10:datastore

# qemu-nbd --connect=/dev/nbd0 -f raw -r pbs:repository=root at pam@192.168.1.10:datastore,snapshot=vm/108/2020-07-14T09:03:47Z,archive=drive-scsi0.img.fidx

# lsblk /dev/nbd0

# mkdir /mnt/test
# mount /dev/nbd0 /mnt/test
