LOQ 16APH8: Can I install ubuntu ?

Hello,

In September, I will be in a cybersecurity training and they told me to switch on Linux because there is some lab I can't do in Windows.

It's okay to buy a second nvme and to do a dualboot ? I don't want to buy a new computer... my LOQ works really well and I also use it to play some games

If it's okay, which nvme and ram is good ? thank you in advance guys
