Wasn't there a version of OSSC that ran off a DE10? Or was that canceled?
The DE 10 OSSC was a prototype for the (at the time of writing) yet unreleased OSSC Pro
Its going to use the same Cyclone V FPGA, but they needed to move away from the DE 10 dev board to do what they wanted.

I think they were going to produce add-on boards for the de-10 so you could run at least some of the OSSC-Pro features on it
That was never the case. They OSSC dev team used a DE 10 for their own R&D only. They OSSC team never intended to make a MiSTer Add-On.
Often in R&D you use various Dev boards that never actually make it in the final revision, the dev board serves as a jumping off point for the OSSC team to work on a FPGA core without worrying about the hardware. Once they got the Core where wanted they ditched the DE 10.
Some of the MiSTer Devs do a similar approach, they use a different dev board that allows them to swap in various actual parts of the console to make sure the parts that they made in FPGA work as they should using a known static variable that is the original part.
And example of this would be using a FPGA board with a MIPS R4300i CPU for a N64 Core Development, as the N64 used a variant of the MIPS R4300i.
You can build the rest of the chips in and circuits in FPGA first and see how they behave with a real CPU before introducing the CPU in the core.
It is my great regret that we live in an age that is proud of machines that think and suspicious of people who try to.
