A change was approved to armbian edge (6.4+ kernels) that adds /boot/dtb/amlogic/meson-gxm-mini-m8s-pro.dtb to the build.
It should be in board type aml-s9xx-box, for edge kernel.
Also with that DTB, the firmware was added to recent armbian-firmware releases, so correct firmware should load automatically. So if using latest (edge) release of armbian for aml-s9xx-box board type, with fdt meson-gxm-mini-m8s-pro.dtb, it should just work

sorry, maybe you have a different version of hardware, but QCA9377/LTM8830
The issue is that the correct fw for QCA9377 bt doesnt load unless

				bluetooth {
					compatible = "brcm,bcm43438-bt";

is actually

				bluetooth {
					compatible = "qcom,qca9377-bt";

i.e. https://github.com/armbian/build/pull/6014/files#diff-8ef15df5363e890e27dba320d674e7fd463f635c99cd049db1e9a15fd55e9122R85
