* Disabled Bluetooth long workqueue (:kconfig:option:`CONFIG_BT_LONG_WQ`).
* Limited the number of key slots in the PSA Crypto core to 10 (:kconfig:option:`CONFIG_MBEDTLS_PSA_KEY_SLOT_COUNT`).

* Disabled the :kconfig:option:`CONFIG_CLOCK_CONTROL_NRF2_GLOBAL_HSFLL_REQ_LOW_FREQ` Kconfig option in the IPC radio image configuration for the nRF54H20 SoC (the option was enabled by default, because clock control is enabled by the MPSL - Multiprotocol Service Layer).
* Disabled the :kconfig:option:`CONFIG_CLOCK_CONTROL_NRF2_GLOBAL_HSFLL_REQ_LOW_FREQ` Kconfig option in the IPC radio image configuration for the nRF54H20 SoC.
The option was enabled by default, because the clock control is enabled by the Multiprotocol Service Layer (MPSL).
This is done to ensure that the radio core requests high Global Domain (GD) frequency.
Bluetooth stack with the SoftDevice Link Layer requires high frequency in GD to make the L2 cache and MRAM run fast to avoid code execution delays.
The :ref:`nrf_desktop_dvfs` running on the application core selects the clock control and enables an automatic low GD frequency request (:kconfig:option:`CONFIG_CLOCK_CONTROL_NRF2_GLOBAL_HSFLL_REQ_LOW_FREQ`), so the application core would not request high frequency in the GD.
