Orange3008, No, there is no need, just put in connector m.2.
I would advise you to make an OS recovery flash drive so that you have an original image of recovery on hand. It is done through a special utility from Acer. You have it installed by default. I do not remember the exact name, before it was Acer Recovery Manager. Now on the new, in my opinion it is called differently.
After that, I would format the HDD and install the OS on the SSD. That is, would not leave 2 OS.
Regarding the form factors, I honestly did not pay attention, but it seemed to me that only the longest SSD could be installed there. For the rest you need to re-solder or solder space for mounting screws, but once
maxx.rway He said that any sizes, then he obviously looked. The key is really any possible, they usually always do that, have not yet seen a laptop with a specific key.

but I don’t understand the difference between Kingston ValueRAM [KVR21N15S8 / 4] and Kingston [KVR21N15S6 / 4]
And this is exactly the memory for the laptops?
More like for pc
The difference is most likely in the location of the memory modules on the PCB, either on one side or on two.
I will not tell you about the SSD, because there you need to look at the controllers of the SSD. Since I did not bother buying SSD for such a form factor, I usually got it for free. I never thought about them. I read only about controllers for full-size SSDs on the Sata connector, but there are several other options, so I think there will be someone who can tell better on SSDs.
