This option depends on the CONFIG_FREERTOS_UNICORE option because RTC fast memory
can be accessed only by PRO_CPU core.

If this option is disabled, the DRAM part of the heap starts right after the .bss section,
within the dram0_0 region. As a result, adding or removing some static variables
will change the available heap size.
If this option is enabled, the DRAM part of the heap starts right after the dram0_0 region,
where its length is set with ESP32_FIXED_STATIC_RAM_SIZE

RAM size dedicated for static variables (.data & .bss sections).
Please note that the actual length will be reduced by BT_RESERVE_DRAM if Bluetooth
controller is enabled.
