nRF5340 Sleep power consumption in Matter over Thread light switch example with SED

Question

Hello, 
 
 I am currently doing my end of career project about the performance of Matter over Thread. I have a working scenario which implies a nRF52840 DK working as a light bulb and a nRF5340 as a light switch. I am measuring the consumption of the devices with an Agilent Power Analyzer and the results of the SED mode that the light switch matter example provides are not what I was expecting. 
 The current consumption in 3v is about 8.3 mA 
 
 I would like to know if it is possible to have a lower consumption for this specific case and if I could change or add some values to the Kconfig file in order to get lower values. I attach my current Kconfig file

 help 
 Use LEDs to render the current state of the device such as the progress of commissioning of 
 the device into a network or the factory reset initiation. Note that setting this option to 
 'n' does not disable the LED indicating the state of the simulated bolt.

 Use this setting to set the default Thread (802.15.4) output power for device that 
 uses FEM. This value has a unit in dBm and represents the Tx power at Antenna port of FEM device. 
 
 # override FEM GAIN to 20 dB as a default 
 # see subsys/mpsl/fem/Kconfig 
 # Leave MPSL_FEM_NRF21540_TX_GAIN_DB unchanged when OPENTHREAD_DEFAULT_TX_POWER=0 
 # to set the output power to a similar value as for nRF52840DK. 
 config MPSL_FEM_NRF21540_TX_GAIN_DB 
 default 20 if OPENTHREAD_DEFAULT_TX_POWER != 0

Finally this is my first post so please if any further information is required do not hesitate to ask me. 
 
 I am hopefully waiting for your recomendations. 
 
 Thanks in advance,
