You can if you don't mind steps at the ends, indexing the cutter up and
across, not unlike a 3D printer would. In micro steps to achieve the
desired angle.
If you want a flat surface at each end you'll need to be able to rotate
the head of the machine to the desired angle, than cut the end faces
with an end mill OR cutting the shape in three settings.
If you have access to a tilting vice you could use that.
Alternatively, make a setting jig to keep your part at the correct angle
in the vice, if there is too much sticking out of the vice you will get
a lot of chatter or vibration as the part bends under the cutting
loads. Machine one then, then turn it round and machine the other.
With slow feeds, a new cutter and small depths of cut you will probably
get away with it.
I used to make objects like this on a lathe with the part held in a
vertical slide and the milling cutter in the chuck, which is yet another
way :-).

an excellent point.
Workholding and fixturing are a huge part of CNC, two excellent books on that are:

You could also use a chamfering router bit if the angle is a common one
like 45 degrees and perhaps multiple passes.

excuse me, bit making 3 tumbles and one handstand to read a book is too complicated. "Goodread" is for non native speaker not very user friendly...
But thanknyou anyway for the hint
