Our only exclusions are for servicing, sterile and implantable items. We use risk assessment to justify varying levels of control over for example reagents purchased for research purposes or for product manufacturing.
Just to clean up some language, only section 7.3 can be "Excluded", all other sections would be "Not Applicable." Make sure to reference it like that in your quality manual. I've seen findings be issued for that despite how ticky tack it is, it's explicitly stated in the document as quoted below.
“If applicable regulatory requirements permit
exclusions of design and development controls, this can be used as a justification for their exclusion from the quality management system.”
“If any requirement in Clauses 6, 7 or 8 of this International Standard is
not applicable due to the activities undertaken by the organization or the nature of the medical device for which the quality management system is applied, the organization does not need to include such a requirement in its quality management system.”
