You absolutely must adjust your embouchure to play notes properly in the
second and third registers.

The "keep the embouchure the same" myth is one of those that stems from a
lack of understanding of the basic physics of the instrument.

I have posted on this before, but suffice it to say that as you go higher
on the instrument and get closer to the natural frequency range of the reed
(1500 to 3000 Hz), the natural modes of the reed effect the playing more
and more. Therefore, the position and pressure of the embouchure on the
reed have a large effect on one's ability to produce notes easily up there.
