If it is just about a couple of seconds you can edit that fragment out and re-upload it. I doubt you can edit the video after this many views. Although they should provide the option when a copyright claim is filed.
I once uploaded a video from a dash-cam that caught a meteor in Russia. It happened minutes after the car was parked and all occupants had left the vehicle. But in the first part of the video you saw the car park and there was a radio playing music which caused a copyright strike. I edited the video, cut the beginning, containing the copyrighted material, out. Then I challenged the strike and added as an explanation that I completely removed the part with copyrighted material from the video. And the strike was retracted. But it was with a new video, normally YT won't let you edit videos that have had to many views.
