Depends on whether CS at each UC or CSU is in a division which accepts IGETC in substitution of its own breadth requirements.
For example, Berkeley L&S CS is in the College of Letters and Science, which accepts IGETC, but Berkeley EECS is in the College of Engineering, which does not accept IGETC.
You can use Welcome to ASSIST
to see whether IGETC can be used for the major at each UC or CSU.
Note, however, that even if IGETC is accepted, in some cases it may be easier to schedule courses articulating to the breadth requirements at the UCs and CSUs than IGETC courses.
