Yes, it definitely can support one of either chip.
Don't have the address at hand - but it takes setup and while read is by direct address - write must use wrapper functions. The address and the setup and write usage are demonstrated in the extRam (?) on github for PaulStoffregen - other threads discussing that as well. Most extensive examples are for SPIFFS on T_4.2 in that code.
The PSRAM 1 or 2 chips is checked in startup before setup() is entered, if found the QSPI processor support for them is enabled, this is NOT the case for the FLASH chip installed given the chip can vary - but only a single source/type of those PSRAM chips is seen present at this time.
