Need help with Error: VC31 WHO_AM_I failed (0)

I've been using nohrm.boot.js which contains:

Bangle.setHRMPower = () => false;

to avoid my device locking up if something enables HRM (e.g. swiping through clkinfo, going into an app which turns it on, etc).

If I load runplus, it seems this is circumvented because it doesn't run boot code, how might I avoid that without hacking runplus?
