Check compatibility with the Z270F motherboard and 300 series chipset.
These chipsets from the 100 and 200 series, such as H110, B250, Z270, etc., are compatible only with 6th and 7th generation systems. The 300 series, including Z370, Z390, B365, etc., are designed for 8th and 9th generation platforms. Although they share the LGA 1151 socket, their electrical designs differ significantly. For future checks, consider using PCPartPicker.com, which offers a compatibility filter to help identify suitable options.
Intel has indicated that certain BIOS updates or modifications can work on 9th generation processors in the 200 series chipset board. This claim is accurate. Whether it's possible depends on your specific hardware configuration and the version of the BIOS you're using.
as others have said, officially no, but you might be able to mod older boards to work, no guarantees on success or stability.
