You will have to ask dell. The processor must be socket, chipset, and bios compatible. Only dell can tell you if it is bios compatible. And, only if the existing processor is NOT soldered to the motherboard.
In my opinion, this upgrade will not benefit you. It is not windows 10 (or 11) compatible, and you will have difficulty getting graphic drivers.
