No I2S boards that I know of but Allo's Revolution USB DAC allows the ESS OSF bypass mode option to be turned on/off via its oled-screen menu. When OSF is off IIRC you have to upsample the source to 8X the base sample rate or something like that. Also with OSF off things like soft-mute, hardware volume and a few other options are not available.
