Thanks Ralph. I am well aware of the different (buffering) options, but
no matter what I tried...still clicks. But it seems I just found the
root-cause. On all versions of Volumio (both the OEM version provided by
MiniDSP, as well as the V2 & V3 releases from Volumio) a service called
“udev” is running (at least on the NanoPi NEO2). Turns out this specific
service is the cause of the clicks. According to the documentation
(https://www.freedesktop.org/software/systemd/man/udev.html#), it’s an
important one. But…rules should be defined to have effect, and none of
those exist. So I safely disabled this specific service and gone are the
clicks, without any side effects:

sudo systemctl disable systemd-udevd.service

Could be beneficial for you too. Thanks again for your support!
