I have an old Tanix TX3-mini s905w 2G/16G (mfgd by Oranth) and I got the VFD display working with Ophub kernel 6.6.50 by modifying (decompiling/editing/recompiling with dtc) the dtb in the following way:

In the dtb I removed the entire section spi {...} (where e.g. led-controller@0 is defined) and removed also the entry for tm1628 in the symbol table (at the end). (The entry for openvfd {...} in the dtb must remain.) After this, the VFD works with the kernel module openvfd present in Ophubs kernels and a openVFD service such as 7Ji's YAopenvfD. The kernel module can be loaded with e.g. armbian-openvfd 18 (after loading the openvfd kernel module the VFD interface is present at /sys/class/leds/openvfd).

With this edit to the dtb the VFD access is no longer controlled by info in the dtb but by the parameters you supply when you load the openvfd module (or so I think, at least).

Edit: I have attached the (edited) dtb that I use. meson-gxl-s905w-tx3-mini-6.6.50-openvfd.dtb.zip
