SRTC on IMXRT1051

We want to implement the RTC clock in a new project with the IMXRT1051 processor using Keil MDK. We already found the SNVS examples which show how to activate the SRTC. SRTC is now running but the power consumption is about 60uA which is too much. Has anyone else used the SRTC and has a smaller power consumption? In SNVS there are also general purpose registers named SNVS->LPGPR which I would need to save some bits for the SRTC, but we are not able to write on it (GPR_SL and  GPR_HL are low and we are in privileged mode). Does anyone have a sample code in which the LPGPR can be written? Thanks
