Question about RSA sigVer e length

This is the capability file I'm using to download a test session.

The question is about the pubExpMode attribute. When I set it to random, the e values I receive contain some 8-byte values, which are incompatible with a 32-bit library. FIPS 186-4 clearly states the range of e as follows.

The exponent e shall be an odd positive integer such that:
2^16 < e < 2^56.
Note that the value of e may be any value that meets constraint 1(b), i.e., e may be
either a fixed value or a random value.

Is there a way to claim random capability for pubExpMode and constrain the test case e values to 32 bits?
