How do I put in a new ssd?

Is there space in a MSI GT75VR for a second nvme ssd?

And if there is, how do I open it up, put it in, and where do I put it?

Do I need to buy any new cables or connectors?

Are there any Youtube videos or advice on how to do it and what I need to know, like what the max size the ssd can be for capacity?

For example is 4TB too big for the machine and the Windows 10 operating system to recognise?
Does the ssd have to be a certain PCIe type like PCIe3 or PCIe4?

It's not to replace the operating system ssd but for storage

Looking at this one there seems to be a couple of different options for drives...

Anyway... if you're talking M2 any Gen3 x4 should suffice. If you're talking 2.5" (cheaper) then any SATA will suffice. Mechanical 2.5" the same applies. Check the height though as your space may be limited to 7.5mm / 9mm and 2.5" drives can come in a larger size like 11mm. If it's an SSD though they tend to fit in 99% of machines w/o having to check the dimensions.
