Booting macOS Mojave from an nvme SSD installed on a PCI-E adapter

[SardusX]

Hi All,
I am updating my multiboot system with a Gigabyte Z390 Designare motherboard. In this motherboard the two M.2 connectors share the bandwidth with the SATA3 connectors according to the following scheme:

In this way, using both M.2 connectors I would lose the possibility of using three SATA3 connectors.
Is it possible to overcome this problem by installing the macOS boot nvme SSD on a PCIe adapter?
Thanks in advance for your help

@SardusX, please update your profile (account details) with your Motherboard, CPU and iGPU or Graphics Card(s).
If you have multiple systems add them to your signature or build signature.

Profiles are mandatory so that others can assist you.

Sorry, I do not know if I can write it here, but I think there's a misunderstanding: my profile is up to date. The question concerns a system (which will have to replace the current one) of which I do not yet have all the parts (but I already have the motherboard) and I tried to complete the configuration. Should I add it anyway?
