Vostro 5620 SSD addition rather than swap possible?

Hello all,

I have the 12th gen i7 one that has a 512 gb ssd. I was wondering if someone can help me out! The specs (to me) for the SSD slots are vague. When looking up on google, it's always about the memory slots and upgrade, not the SSD. I want to be able to add a second internal SSD. Is this possible? Thank you!

ps. hope laptop stuff is ok here. I posted in laptops and didn't get a reply. Thank you community!
