This series is limited to what Apple released [https://everymac.com/ultimate-mac-lookup/?search_keywords=iMac18,3|iMac18,3]. In this case the best you could install would be a 4.2 GHz Core i7 (I7-7700K).
While all of them use the same socket (FCLGA1151) The RAM speeds are also different DDR4-2133 Vs DDR4-2666 the logic board is not able to support it. And lastly the TDP this system requires is 91 W Vs the hotter 95 W CPU’s. The systems firmware won’t recognize the CPU.
