Yes. Ideally stardrive 1 would be the step up. But it's not and our BlackBox code mod is not ready yet.
Else... Sword of the stars has very good RTS combat but it's turn based empire management. It was for it's time best in class of turn based RTS hybrid https://showbox.bio/.
Stellaris is full RTS but it's combat is far more strategic.
Starruler 2 is full RTS with full ship design but not very tactical and it's got unusual mechanics https://tutuapp.uno/.
Distant worlds is full RTS and very deep empire management but it's no where near as pretty and ship design is lacking but there.
There are others but good RTS 4x was only really designed right in stardrive 1 but it will never get past the release stage so it's buggy and content lite https://vidmate.cool/.
If graphics aren't your major point then distant worlds is likely the best option but it's complicated.
Is Dawn of Andromeda full RTS? That might be an actual step up from sins.
