Install Debian on WD My Cloud home

Hi all, is there any way to install a clean Debian version on it (without OMV)?

What it the process (step-by-step) to generate the three zip (debian system split in three parts) inside the USB installer? Because I want to install Debian 10 (which seems to be archived for Home Cloud Duo Intalling Open Media Vault (alpha state) (finished, there is an easier method now, i keep the post for research data)))

Thanks.
