What are my upgrade options for the AN515-58-78ZC?

Hi all!

I have an

AN515-58-78ZC

Nitro Laptop, which I got for myself a year or 2 years back, and I was wondering what Upgrades I can make to the laptop? I am looking to add more storage and upgrade one of the RAM sticks. However, I am unable to find such info on the internet, and I am currently in a place where I cant take it apart to see what it has, so my questions are:

1) I am looking to add another SS; however does the Laptop come with 2 M.2 Slots or 1 M.2 and 1 SATA?

2) I am assuming the Max Ram Upgrade is 64 GB.? are the RAM sticks DDR4 or DDR5? I am assuming they are both 8 GB, since the laptop has only 16 GB right now

3) What type of screw is used in the back cover of the laptop? And what size Screwdriver head do I use?

Thank you very much for the help
