How can I set the value of plain_modulus is CKKS? #641

Hello, I need to have an specific plain_modulus in a code, and whenever I try to change it and set a value it says that it is not allowed for CKKS. How can I change that? Is there a way to set the other parameters in order to give the plain_modulus a certain value? Thank you

According to my understanding, CKKS scheme does not need to set plain_modulus. Both CKKS ciphertext and plaintext use same RNS component. Please refer source code in example 2_encoders.cpp or CKKS encoding scheme.
