I always enable disk encryption, but I wonder why Linux doesn’t support secure boot and TPM based encryption ( I know that Ubuntu has plans for the later that’s why I’m considering it rn )

There is at least one that, as of recently, offers both out of the box: OpenSUSE Aeon. In fact, TPM-based encryption is now mandatory.

It’s rolling—based on OpenSUSE Tumbleweed—and atomic.

I need something that keeps things updated and adobts newer standards fast ( that’s why I picked Fedora KDE in the first place ), I also use lots of graphical tools and video editing software, so I need the proprietary Nvidia drivers

This could be another point in Aeon’s favor: it uses a combination of Flatpaks and Distrobox, meaning you can use software from basically any distribution you desire—including from, say, Arch’s AUR.

I’ll warn you ahead of time: Aeon and its developer are very opinionated. It’s basically one person’s idea of what makes “the best desktop Linux system,” and those are Richard’s words, not mine. It is also currently still in the release candidate stage.
