I have a Canon 750D equipped with a EFS 18-135mm [edited] lens (and sigma macro) and now I updated to a Canon R6 Mkii using this EFS lens through an adapter and also bought a Canon Macro R100 mm. In the 750D, when the setting on the lens is auto focus (AFS), I could press halfway the shutter and adjust/fine tune the focus with the ring. This was useful to me. If I remember I could even employ the digital magnification
In the R6ii, this function is not working at all, with either lenses (EFS and Macro). When shutter is half down, the ring has no effect. (It works only when manual focus is selected). I hope that this can be resolved by some setting in the camera. I shoot in M mode.
Thank you

Manual Focus Override has to be enabled in the camera by default its disabled on the EOS R cameras. On DSLRs it was enabled by default. I also think you mean "One Shot" Canon has never had a mode called "AFS" that is a Nikon and Sony term. It should be set to One Shot enabled. This setting has been around since 1987. Canon has had focus by wire lenses since the beginning of the EOS system. The first of such lenses was the EF 300mm F/2.8L USM lens released in 1987. All early Ring Type USM lenses provided Manual Focus Override electrically instead of mechanically like newer Ring Type USM lenses. Also note Manual Focus Override doesn't work when the camera is set to Servo AF or AI Focus. This is because you would be fighting against the camera's AF system. The restriction has been in place since 1987 and there is no way around this restriction.

Lens Electronic MF and Electronic Full Time MF have to be enabled. Along with the camera seto to One Shot AF. If it's set to Servo AF or AI Focus the focus ring is ignored.

Thank you everyone. Yes, i managed now through that menu [AF]. It is working as I intended / wished. I am experimenting a bit more as there are dozens of options and settings in the menu. Special thanks to Deebatman (sorry I posted my screenshot after yr solution because I did not refresh the page and did not see yr messages).
The outer ring seems to be customisable (I had success in P mode which sets the EV setting) but it does nothing at the moment in the M. Coool!!!

You set up the control ring on the lens for Exposure Compensation which isn't available in Manual Mode. Unless you have ISO set to Auto. That's why its not working in Manual Mode.

I would agree with my colleague Demetrius that if you want to replace your EF-18-135 IS STM with an RF full-frame optic (which is would strongly encourage since you paid for a 24MP FF sensor) then the RF 24-240 is an excellent option. It punches way above its price point.
The are sometimes available from the Canon USA Refurb store. These lenses might be overstock but new, new but open box, show or demo units, but 'good as new' with a Canon warranty and a discount. If they are out of stock you can request to be notified when they are in.
