Hi,

There is no setting to turn off the light. Try covering the light with a small piece of electrical tape.

If you are using the remote that came with the Roku 3 you do not have to worry about covering the IR sensor, the supplied remote is RF.

There is this product (even though not available from them at this time - maybe somewhere else)

There is also further info in this link
