STM32CubeWBA V1.7.0 – New UTIL timer used for HAL tick increment in MX_APPE_Init()

After updating to STM32CubeMX 6.15.0 with STM32CubeWBA FW V1.7.0 for the STM32WBA63CIUx, I noticed a change in how the HAL tick is driven.

In MX_APPE_Init() (generated in app_entry.c), CubeMX now creates a UTIL timer to increment the HAL tick:

 /* Create an RTC based timer to trigger HAL tick increment */
 UTIL_TIMER_Create(&TimerHALtick_Id,
 HAL_TICK_FREQ_100HZ,
 UTIL_TIMER_PERIODIC,
 &TimerHALtickCB, 0);
 uwTickFreq = HAL_TICK_FREQ_100HZ;

 /* Start HAL tick timer */
 UTIL_TIMER_StartWithPeriod(&TimerHALtick_Id, HAL_TICK_FREQ_100HZ);

This runs at 100 Hz by default and causes my system to wake every 10 ms.

Previously, I used TIM17 for the HAL tick, with FreeRTOS (tickless idle) and STM32_WPAN BLE, and it worked well. Now, I see both TIM17 and this new UTIL timer, which leads to unnecessary wakeups.

My questions:

1. Is there official documentation on this new HAL tick implementation using UTIL_TIMER?

2. How can it be configured or disabled via STM32CubeMX instead of modifying the generated code?

3. If I want a 1 ms HAL tick, should I reconfigure the UTIL timer to 1000 Hz, or simply disable it and keep using TIM17?

4. What is the intended use case for this change in FW V1.7.0?

I could not find any CubeMX option to select between TIM17 and this UTIL timer. Any guidance or reference to documentation would be appreciated.
