Microcodes revision on the same CPUID

Hi, everyone! I am planning on installing the 906EA revision 70, such that I can eliminate the spectre and meltdown patch. Now, I have an i3-9100F, and on many manufacturers site they all say that 9th gen has become available on their motherboard later on, so me being able to confirm that this revision works with my CPU is pretty impossible unless I test it. Problem is that I don’t have a programmer, neither certain functions to roll back the bios. So, my question is: if there are more revision of the same CPUID, can those impact compatibility, as in from a certain revision more CPUs are supported? (to be noted that 906EA is also shared by most 8th gen CPUs as well)
