In each NOC description there is a section EDUCATION REQUIREMENTS which will state whether there are any education requirements that are suggested as necessary or MAY be or usually required to go with the job duties.
Anyone here could give a general answer and say job doesnt matter if not related to education but it is what is stated for a specific job that is important, there is no one size fits all and ultimately IRCC will decide on the importance of job duties versus any education requirements.
Maybe share here the jobs you are thinking about and what your qualifications are .
