Dewalt 611 precision collet and nut questrion : Can I use "any" ER20 collets with this setup?

Can I use “any” ER20 collets with this setup?

No. The DeWalt spindle is unique and won’t fit any ER sized collets.

My apologies I reference the precision collet adapter available here in the invenables store. It uses an er20? But I’m not sure if it is modified or not.
