is it possible to disable HAL/Arduino handling of a specific timer interrupt?

[PerennialNovice]

I saw that in HardwareTimer.cpp timer-ISR are surrounded by preprocessor conditions like #if defined(TIM2_BASE)
I tried using #undef TIM2_BASE in the arduino setup() functions but that did not work as hoped

Is there a possibility to disable certain timers (or part of other peripheral) instead of completely disabling like with HAL_TIM_MODULE_ONLY or HAL_TIM_MODULE_DISABLED?

This is the CMSIS device definition (header file). When you undef in setup it is local to the cpp file (.ino). Even if you disable it globally, I do not advise as it is probably used by LL/HAL source files and CMSIS one.

Finally to answer your title question, no it is not possible. The only way is to use HAL_TIM_MODULE_ONLY to globally disable the usage of the HAL_TIM_MODULE by the Arduino API level.
