JazakAllahu Khayran. Is it kufr to deny some variations found within the mutawatir qira’at, such as the differences between the rawis and turuqs? Would it also be kufr to say "I neither confirm nor deny them"?
yes all of this is the revealed qur'an. what does 'doubt' mean? one needs to accept in general, that the the qur'an was revealed in 7 qira'at - irrespective of whether one understands or knows about the variations and identifies them. Allah ta'ala knows best.
There are some variations found within the mutawatir qira’at, such as the differences between the rawis and turuqs. is it fardh to believe that they are part of the Quran? What is the ruling on someone who doubts them?
