For the original (obsolete) Arduboy library this is true, but in the (now recommended) Arduboy2 library the beginNoLogo() function has been removed.
The proper way to do it with the Arduboy2 library is to use boot() instead of begin(). This will do a minimal hardware initialisation without any of the extra boot features that begin() performs. You can then add back in any desired boot features by calling their functions from the sketch after boot(). Currently available boot features are: system audio mute control, flashlight mode, and the boot logo.
The begin() function also first calls blank() to clear the display, and audio.begin at the end to set up the speaker pins. You may have to do this after calling boot() as well.
All of this is described in the README file in the GitHub repository for Arduboy2 and in the online documentation as well.
If you're developing a sketch and want to disable the boot features just to speed up development, and you have enough code space left over when you're ready to release it, it's desirable to switch back to using begin() so that users will get the standard Arduboy boot experience and features.
