Hi, I think they come as a side effect of the Enable Towers option.
Maybe they try to support the supports of the holes.
Try to switch to only buildplate, maybe they are gone then.
I don't think this part needs any support. Or at least enable support only touching buildplate as conny_g says. Personally I rarely use cura support and instead generate the support myself in cad. I would create two arches in the front and back of that large cylinder and do zero support in between (let it bridge across the arches.

And here's a screengrab showing nothing needing support in these areas:
Thanks!
