SARADC with triggered buffer (IIO)

Greetings!

Is it possible to read data from SARADC using a IIO’s triggered buffer?
In kernel 6.6.2, after enabling any channel (./scan_elements/in_voltageX_en) and buffer length setup (./buffer/length), activation of the buffer (echo 1 > ./buffer/enable) fails with an error 'write error: Invalid argument'. SARADC driver does not provide a separate trigger, so ./trigger/current_trigger is empty.
