pretty sure that the whole point of neuralink is that you can't radio-interface with brains in this way
there is a microwave tech that can induce sound in the cochlea but there is slim to no other organs of sufficiently large size that can resonate with radio signals and induce nerve sensations, aside from the generalised millimetre wave heat induction denial attack
the progress of DNA technology is far from being able to capture even a fraction of the distinctive elements of cellular DNA, they still need to take a clean sample, run it through PCR to get enough copies that they can then use X-ray (yes x-ray) chromatography to decode the "bits" of the DNA code, and then, it has to be deduplicated and sorted in order based on markers, this is what the Human Genome Project was about - discovering all the fingerprint markers that *merely signify human DNA* - and in any case, *only from the use of PCR and x-ray chromatography*
so, no
if they had the level of tech they could identify you non-invasively by DNA samples that are at natural normal levels of percentage per mass, they wouldn't bother hacking your phone or internet service provider to spy on you
one of the key technologies of these people that you, and most people who believe in the omnipotence of spook agencies, do not understand, is counterintelligence, and the principle that you can defeat an enemy by making them think you are too powerful
every time you see someone repeating this meme, you are watching them regurgitate covert mind control programs that have been inserted into movies, media, and press to fool most people into submission
i am not one of these... if the tech exists, and it isn't billions of dollars per unit, it is in the marketplace, to pay for the research...
