STM32H563 / H573 Dual-Single SPI as a double write only master

Hi Experts,

Is it possible to use STM32H5 OctoSPI interface (configured as Dual-Single-SPI) as two individual transmit-only SPI masters?

Requirements:
1. Two devices connected to MCU are identical but receive different data
2. Devices are not a memory
3. No data needs to be received by MCU
4. No simultaneous write is required

If such configuration is possible, how will HAL code look like?
Which of OCTOSPI_IO0, IO1, IO2, IO3 pins are can be configured as 'MOSI'?

Edit: I realized 'Dual SPI' and 'Dual-Single SPI' are a different things. Changed post subject to 'Dual-Single SPI'
