Hi Harneet,
Welcome to the thread! As a personnel manager, your title matches the NOC 0112- HR Manager. Refer to
https://noc.esdc.gc.ca/Structure/NocProfile?objectid=JMiDyl9H42W7/vVQhmVOFIwDf+10OiLsJgTk4bE7QBA= for matching your job responsibilities. If it matches at least 60%, you are good to go. Just that while getting reference letters you would need to input these responsibilities and it must match with the roles mentioned on the page.
Now, coming to your question. NOC 0112 just requires you to have a bachelor's degree preferably in commerce/ psychology/ personnel management. But even if you have a bachelor's in a non-related field, there's nothing to worry as long as you have sufficient work experience. So technically you don't have any degree requirements for any of the HR related NOC's mentioned in this thread.
However, while you do need to have a CHRP certification if you intend to work as an HR manager in Canada, you won't require any additional qualification to submit your Express entry profile. So, for your immigration purpose you really don't need anything additional to move forward with your application.
Stop wasting time and proceed with your application mate!
Cheers,
Joel
