As it looks, unfortunately not. However, if the keyboard were theoretically available with a DE layout, you could contact customer support and ask for the product to be included. Only then will it become clear whether it is possible.

Hello I play with it on the ps4 and it works smoothly I think it's the same with the ps5 - but I can't guarantee it

Unfortunately, we do not have any information on this yet. Should the product become available to us, we will consider a possible inclusion. :)

no unfortunately not

Es fehlen halt die MAC spezifischen Tasten. Ansonsten siehe Kompatibilität https://www.logitechg.com/de-ch/products/gaming-keyboards/pro-mechanical-gaming-keyboard.html

The keyboard has a small shift key. Attention: It has a German (Deutschland!) keyboard layout.

Unfortunately, we have no information whether there will be a CH version. According to the manufacturer's number, the GL Clicky is installed in this version.

No, the manufacturer itself only builds/sells the black version of this keyboard with GX Blue switches. (Source: https://www.logitechg.com/de-ch/products/gaming-keyboards/pro-mechanical-gaming-keyboard.html)

DE = QWERTZ, with accents : ö, ä and ü (Germany and Swiss German) CH = QWERTZ, with accents : é, à and è (French-speaking Switzerland) This keyboard is DE.

No, sorry.
