I am also a portuguese non habitual resident.
Hi, and welcome to the forum from me.
This isn't an answer to your question, I'm afraid, but it is something it might be best to be absolutely clear on from your point of view.
Non-habitual residency has a very specific meaning in Portugal - it is a tax status conferring various potential benefits which is only available to new residents and applies for a maximum period of 10 years, non-renewable. The main criteria for eligibility are 1) that you have transferred your residence to Portugal and 2) that you have not been tax resident in Portugal in any of the previous 5 years.
Although it is possible to have acquired the status and subsequently departed, suspending the application of NHR but with the option of resuming the status should you return within any of the remaining 10 years counting from the start date, it seems unlikely from what you have said that that applies to you.
You may just be using rather inaccurate terminology, of course, but given that NHR implies you being registered with the tax authority in Portugal as being resident in PT and that there are obligations associated with that, you might want to check as to whether you really are registered as a beneficiary of the Portuguese non-habitual resident tax regime.
