Applying ESXi Patch ESXi650-202005401-SG

Hi,

just had a question about applying a ESXi patch recently released

My ESXi 6.5 U2 Patch 3.

I have been told by VMware Support that applying the subject patch on my ESXi host will take my ESXi to 6.5 Update 3.

I dont want my ESXi to be updated to ESXi 6.5 Update 3. (some compatibility issues)

I find it difficult to accept that applying a patch which fixes a certain vulnerability requires your ESXi update version to also be upgraded.

appreciate any inputs which can clear this out for me..
