Question about Samsung 860 Evo

Yes, that's no problem.
Unscrew your AllinOne and see if it is an m.2 memory or a 2.5" hard drive.
If you don't know what m.2 or 2.5" ssd is, google the terms and look at the pictures.
You can also google Pavilion 24-r070nz and search for videos and you will find a suitable video to take an AllinOne apart.

@rolandniki the 2TB variant is available for just under 170chf here https://www.preispirat.ch/samsung-86...
