-            Note that, this option only controls the RMT driver log, won't affect other drivers.
+            If enabled, RMT driver component will:
+            1. ignore the global logging settings
+            2. compile all log messages into the binary
+            3. set the runtime log level to VERBOSE
+            Please enable this option by caution, as it will increase the binary size.
