Dual boot ubuntu + coreelec via ssd

Hi guys,
Recently i bought a vim4 and i wish to install ubuntu via oowoo on ssd m.2 and coreelec, my question, it’s possible to install booth in the same ssd? it’s possible the dual boot? primary ubuntu secondary coreelec. is there a script that shows the option to boot one system or another?

regards

Ok, then I answer myself, as I have read there is still no support for booting from NV, I understand.

Now I ask the forum, will that support arrive? Will there be a possibility of booting from NVME and having dual boot?
