Microcontroller HyperBus interface with external PSRAM

Hey. I am using STM32F412 microcontroller which has FSMC (Flexible static memory controller) interface. I need to use an external RAM (SRAM or PSRAM) 16-32MB . The only relevant PSRAM chips with that size I could find are something like those : https://www.cypress.com/file/183506/download
and they use HyperBus interface.
Is there any way to use HyperBus PSRAM without swapping to a microcontorller that has HyperBus interface such as STM32L4+
