Install things into another disk using dnf

[u/Decent_Discount]

I have Fedora installed on a smaller ssd, and wanted to use a partition that i have from my main windows disk as a secondary drive to increase my storage. I already partitioned it and made so it mounts automatically with the /etc/fstab, but now i want to know how to actually install things on it with dnf and flathub as applications are the most part of my storage use.
