How to do encrypted manual install of manjaro on dual boot system?

I am new to manjaro and I am planning to install manjaro along with windows 10. I found many tutorials for dual manual installing manjaro without encryption. But I didnt find any tutorials or articles related to an encrypted install of manjaro along with windows 10. I have found this image of manjaro installation which has an encrypt checkbox.

  • Can anyone tell me after selecting selecting encrypt option how do we encrypt manjaro?

  • Do I have to encrypt /boot , /boot/efi, /root, /home and /swap partitions ?

  • If I only encrypt /root , /home and /swap alone will that be secure
