There is a road hydraulic group L-twoo R9 2x11 for gravel.

I want to install an MTB cassette and, accordingly, a rear derailleur with a damper

But there are no 11-speed GR9 rear derailleurs for sale.

Only visually identical 10-speed GR7 and 12-speed GRT are sold (https://aliexpress.ru/item/1005005496048529.html), as well as MTB L-twoo T9 at 11 speed, which looks exactly the same (https: // aliexpress.ru/item/1005005981719066.html)

Are the rear derailleurs R9, GR7, GR9, GRT, T9 compatible with each other in terms of pull ratio?
