No need to remove clamp from rubber boot.
There is only one c-clip on the inboard side of the CV joint. . Circled in red
Remove the c-clip. At that point the axle can be removed from the CV joint
Be warned that that the axle may not easily come out of the CV joint. Often the splines get buggered up at the notch for the c-clip. Careful bevelling of the sharp splines around the circumference of the notch will help ease axle removal.
Once axle is removed from the CV, the rubber boot and metal boot flange can be removed from the axle as an assembly once you remove the circular spring washer #22 in diagram that will otherwise prevent the small end of the boot from being removed from the axle if it gets hung up in the circlip notch.
