Resetting over SWD without nRST in standby mode

Hi,

I have an STM32L15x. Is it possible to reset the microcontroller only over SWCLK and SWDIO without the reset pin when the microcontroller is in standby mode?

I can access the target ID over SWD even though the device is in standby so I suppose the debug unit is not completely powered down. Programming or debugging however is not possible.

The use case is a product that is programmable over SWD but with as few connectors to outside as possible.
