Can you delete an accessibility?

[AC Question]

EVERY TIME I TURN MY PHONE OFF, WHEN I TURN IT BACK ON....THE "TALKBALK" IS ACTIVATED EVEN THOUGH IT SAYS OFF......AND IT TAKES LIKE 5 MINS OF PLAYING WITH IT( TAPPING OFF and thenTAPPING OK ONCE IT REGISTERS )
VERY ANNOYING.... WISH I COULD DELETE THE WHOLE FEATURE!!
