It all depends on the construction of the unit. Is it one unit or are the door and sidelight independent units? If independent, you can do it. If one, will be tricky.

I’m thinking all one unit?

I agree, looks like 1 unit. What don't you like about the sidelights you're seeing with doors you like?

I just don’t like the designs in them, they look to elegant for the style of house. And I’d rather not buy blinds for a clear one.

You can put "rice paper" or other designs that will cover the plain glass. Lowe's and HD carry them.

Go to a local lumberyard. They can configure any combination of door and sidelight usually with dozens of standard glass options.

You need to pull that piece of trim between the sidelight & door to know if you have a one piece assembly or a ganged assembly. Ours was ganged to we were able to replace the sidelights and leave the door.

Why not a post a pic of your house and the door. BTW why blinds at all on a door unless the heat or UV rays are an issue? We have no clue as to your style but IMO you start taking apart something you better know how to put it back together .
