I think you are after *dmesg -n alert*

man dmesg
...
        -n, --console-level level
               Set  the level at which printing of messages is done to 
the con‐
               sole.  The level is a level number or abbreviation of 
the  level
               name.  For all supported levels see the --help output.

               For  example,  -n  1  or  -n alert prevents all messages, 
except
               emergency (panic) messages, from appearing on the 
console.   All
               levels  of  messages  are  still  written to /proc/kmsg, 
so sys‐
               logd(8) can still be used to control exactly where 
kernel  mes‐
               sages  appear.  When the -n option is used, dmesg will 
not print
               or clear the kernel ring buffer.
