Those new dura ace chain bolt recently developed by velobike have solved this particular drivetrain issue , it worked very well for me with the recommended thread lock bond , it's very strong and safe ,I do a lot of back pedal and I was concerned about the original dura ace chain link , also no more need to loose the wheels to wax the chain.
Thank you velobike ,:

Ok, what are we talking about here?! Why would I want that?

That's the questions you probably have.

Just when I was finishing building my track bike (which is my road bike too), I was wondering which ratio to put. I already had a Dura Ace 11s chain waxed, and couldn't figure out the ratio and didn't wanted to buy 10 quick link from shim'.

And.... Vélo bike posted, on IG, this. Like it was intended for me.... So I bought it.
Installed it (put some loctite!) and it works!

Would I ride under the rain? Maybe. Did I changed the ratio yet? Nope.

But I know I have the perfect accessories to add links to my chain.

I had no idea these existed. Such a relief for me to be able to easily remove my 11sp chain for re waxing.
