If an individual who is non resident for tax purposes for the 25/26 tax year, leaving mid April and returning only at Christmas for a few days, makes a listed shares disposal at some point in the future, will that disposal be CGT exempt assuming the individual remains non resident until the 29/30 tax year has ended ie 6th April 2030?

I understand to be considered non resident when working full time abroad one must average at least 35 hours a week during the reference working period, work less than 30 days in the UK and spend less than 91 days in total. Firstly: If one wanted to spend 7 weeks in the UK in one block and work for 3 of those, by the end of the period the individual would NOT have fulfilled the “at least one overseas workday in every 31 days” - is that correct? Would the individual have to make a short stop back to their normal overseas workplace to remain compliant, during their 7 week UK stint? secondly: what is the formal definition of full time work abroad particularly for self employed individuals ?
