Nintendo Switch Firmware Update 12.0.0 Reportedly Adds Internal Dock Update Support
Nintendo Switch has been updated to version 12.0.0 and this comes with some hidden changes as discovered in the datamine of the firmware.
While the official changelog for this firmware mentions that it is related to the save data backup feature. There was an issue with this feature that resulted in the data not being backed up and getting interrupted in the middle, which has been resolved now with the new firmware update.

Another popular modder suggests that this update has added the ability to update the dock for the Switch. This could be one of the features that can be potentially used in a new hardware revision. It has been rumored that the new Switch will come with an updated dock that can output in 4K.

Can’t see an obvious reason why.

However, all of this is pure speculation at this point. While it is certainly possible that this new reference has been added to the Nintendo Switch with a firmware update, there is no official announcement of a potential new hardware revision so we can only speculate for now.
