ᐅ Retrofitting Residual Current Devices (RCDs) in Older Electrical Systems

Hello,
as some of you have already read, I am currently renovating one of my 1.5-room apartments. Unfortunately, there is no RCD (residual current device) installed in this apartment. I would of course like to have one added.
Since I don’t really know much about electronics, I wanted to ask for your advice before calling an electrician. As you can see in the photos, there are already outlets with green-yellow protective earth (bathroom, kitchen, partly in the living room), but also outlets without green-yellow protective earth (also in the living room).
The photo with the black/red/gray cable shows a switch.
Now the crucial question: Is it possible to retrofit an RCD without having to break open all the walls? If there were a green-yellow protective earth conductor everywhere, I would have said yes—at least based on what I have read. With a "neutraling" system (i.e., without this protective earth), no.
But how does it look here? I don’t want to tear open the entire walls. If retrofitting is not possible, I would probably install RCD-protected outlets in the bathroom and possibly the kitchen.
Best regards
