Dkms install --no-depmod zfs/2.1.12 -k 5.15.85-1-MANJARO - kernel does not include the required loadable module support

if possible or older but with ZFS support (ZFS is on my external drive which i rarely use)

Yes, that is possible. I use ZFS on my dual external drives via SATA connection (not USB connection) for NAS and my second weekly backup.

The solution:
Idea: You can use two separate Kernels running in parallel on the same computer. How?
You need to setup a new KVM/QEMU to connect to ZFS on any drive on the same computer.
I would suggest, try to install TrueNAS SCALE on QEMU/KVM. TrueNAS SCALE OS with Web GUI might be good for ZFS beginners. But I use Arch ZFS LTS that is not easy for beginner.

[Unstable Update] 2023-02-17 - Plasma 5.27 LTS, GNOME, Python

Best solution for me: I created a new KVM/QEMU to setup a small NAS with separate Kernel 6.1 LTS and ZFS that directly access my external physical disks as pass-through disks via PCI without virtual. Host: Kernel 6.2 is now running on my PC without ZFS. Guest: Kernel 6.1 LTS is running on my KVM with ZFS on the same PC. Both communicate via a local NFS share (Speed ~31Gb/s). NFS preserves all file permissions , Samba does not.

ZFS pools do not load during boot (manually importing works)

Try to install linux-61-zfs instead zfs-dkms, because zfs-dkms often breaks compatibility with current latest version of Kernel. But I believe that linux-61-zfs requires some specific path-versions of Kernel 6.1. (not all path-versions of 6.1) PS: I don’t use ZFS on my main system, but my idea was to have two separate Linux kernels running in parallel on my same computer. The second Kernel LTS with ZFS module zfs-linux-lts runs on KVM/QEMU to access my ZFS pool on my two external physical dis…
