I have successfully updated the U-Boot splash screen and disabled all the output on console, but the U-Boot version is still printed (it’s printed before the U-Boot output).

I’m not sure what exactly you mean by “printed” resp. where that is. Are you talking about the serial debug console or any graphical display and if so what kind?
By “printed” I mean text output on the serial console.
I have disabled the console on my lcd display (console is tty1 I believe), but it still shows the “U-Boot 2016.11-2.7.2+g60021a4 (Aug 14 2017 - 10:13:21 +0200)” output.
