Aspire R14 (R3-471T-35G3) Upgrades

I saw on this page (http://www.acer.com/datasheets/2016/4876/R3-471T/NX.GH1SP.002.html) that my laptop has a maximum memory of 12GB. I planning to upgrade since I'm having trouble running MATLAB and Microsoft Teams. These two use up a lot of RAM. I'm also running out of space due to a lot of engineering programs and files.

I have a few questions about the upgrade:
1. Can I upgrade my HDD to an SSD?
2. Does my laptop have a slot for M.2 SSD? I was not able to see any info regarding the sockets on my laptop.
3. Can I really upgrade my RAM to 12GB? I saw older posts that the R14 does not support additional memory.
