No. Even if you have to move it a bit, the appliance connector has a degree of flexibility. That looks like foil and wire duct. You might want to think about replacing it. I don't think they are the greatest and flexible metal is better. Solid metal is best.

Boy, you shut off sure is rusty.

I ran mine on 'fluff' and cleaned it from the outside. Lint was blown out by the dryer.

You should get rid of your "soft duct".
Soft ducts are the #1 cause of dryer fires.

Yes, a hard metal flexible duct is safer.
