That's like calling the flappy paddle AT in the FRS the same 'thing' as the flappy paddle AT in a GTR.
VTEC has variable lift profiles, the valve lift is changed along with timing and ignition.

Toyota's VVT-i does not do this, it's literally in the name 'variable valve timing ignition'. Toyota does have a vtec like system (VVTL-i), but this engine actually uses Subaru's variable valve timing (my mistake for calling out vvti), which also does not alter valve lift like vtec does.

tldr
AVCS =/= VTEC
