No, the Mark will be presented literally as the Mark and you will choose to accept it in the full knowledge of what it is - there can be no subterfuge surrounding it or tricking people into unwittingly getting it; you have to choose to receive it knowing full well that it represents the Beast.

So secret microchips or hidden chemicals cannot be it, as they are not overt.

Not saying that the vax is the mark since i dont think it lines up well with the events that are supposed to happen before. However whatever the mark is you can indeed get tricked into tacking it and into worshiping the beast
(rev 19:20) And the beast was taken, and with him the false prophet who wrought miracles in his presence, by which he deceived them that had received the mark of the beast, and them that worshiped his image. These both were cast alive into a lake of fire, burning with brimstone.
