With Ubuntu bionic, kernel 4.15.0-11-generic #12-Ubuntu SMP Fri Feb 23 18:38:46 UTC 2018 s390x, I did not see any effect when switching kernel parameter between nobp=1 (secure) and nobp=0 (faster, but insecure). In the kenel config I could not find any option mentioning nobp either.
Attaching kernel config.

The default should be nobp=1 with bionic
