If there a way to insert custom parameters into the GOST 2001 parameters set programmatically and what API should be used? After being managed to generate EVP_PKEY by simulating OpenSSLs' function I found out that parameters are bound to NID, so there's a need in adding custom ones there. Ideas anyone?

Problem solved next way:
FILL_GOST2001_PARAMS:unsupported parameter setappears if you don't set yourCurveNameas one of already existing parameter set NID, so it should be like this:EC_GROUP_set_curve_name(CurveGroup,NID_id_GostR3410_2001_TestParamSet).EC_KEY_check_key()function, you call it. What OpenSSL does is - it takes parameters from yourEC_KEYobject, so it's easily customizable, as long as those are correct (point is on curve and etc.).
