You could edit /etc/default/grub and add, acpi=off at the end of GRUB_CMDLINE_LINUX_DEFAULT
e.g. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off" then sudo update-grub and reboot.

acpi=off disables some features, i only want hide those messages.

Hi, I solved it with a simple parameter loglevel=0
https://wiki.archlinux.org/index.php/Silent_boot#Kernel_parameters
GRUB_CMDLINE_LINUX_DEFAULT="quiet loglevel=0 splash"
