I also wanted to highlight the reason for this madness from Bafang removing self-modification features.
In the old version of EN15194 there was not requirement for locking anti-tampering measures, however:
The latest standard EN15194:2017, sadly enough includes a section pushed by Bosch and Shimano lobyists, this also makes the EN15194:2017 inherently incompatible with any DIY or repair community/mentality.
Luckily, and in contrast to populair opinion, EN15194 is not a European requirement for ebikes!
It's a tool: if you comply with EN15194, you are guaranteed to comply to the relevant portions of the "Machine Directive".
It depends on the country in question if they actually require EN15194 compliance for ebikes to be used on the road. For example the BeNeLux does not.
However: I sincerely doubt if a judge is going to find your bike "non-compliant", just because you didn't add anti-competitive practices to your self-build bike.

NEN-EN 15194:2017
4.2.17.1 General
Anti-tampering measures apply to tampering or modifications that general consumers carry out
concerning the control unit, drive unit or other parts of power assisting system by using commercially
available tools, equipment or parts.
4.2.17.2 Prevention of tampering of the motor
The following anti-tampering requirements shall be taken into account:
a) Anti-tampering relevant parameters indicated below shall only be accessible to the manufacturer
or authorized persons and changes of software configuration parameters require programming
tools that are not commercially available or security protected:
1) maximum speed with motor assistance (all systems),
2) parameters affecting the maximum vehicle speed limited by design,
3) maximum gear ratio (system with middle motors),
4) maximum motor power (all systems),
5) maximum speed of starting up assistance;
b) Assumable manipulations on the approval relevant configuration shall be prevented or
compensated by effective counter measures, i.e. plausibility logics to detect manipulations on
sensors;
c) Closed set of components (i.e. operation only with released battery);
d) Protection against opening of relevant components without traces (sealing).
