Can QSPI1 & QSPI0 be active at the same time?

I'm currently working on an application that runs on a Vybrid MPU.

The application uses QSPI0 for the NOR FLASH access, and QSPI for a serial SRAM (NO1S830HA) access.

Both interfaces have to be active at the same time,

and as far as I've seen in your demo examples (configurations : svf522revb_m4, svf522revb_a5,twrvf65gs10_a5 and twrvf65gs10_m4) this option is disabled by software.

Since we are currently experiencing problems in the testing, I would have like to know whether this mode of operation is possible,

and if so - under which circumstances and what needs to be done in order to ensure its proper functioning.

     Thanks in advance,
