Can I setup Sonoff T1 (TX series) switch to detached relay mode without flashing Tasmota?

I have purchased few Sonoff T1 and T2 switches (TX Series - SONOFF Official) and want to setup to use with Phillips Wiz Downlight.

Since now Sonoff has officially support for HA, but I can’t find a way to configure the switch as detached relay mode, so that I can control the Wiz light without turn-off the switch.

Anyone know is that possible to set it as detach relay mode?
