You'd have to write directly into the attribute files.
For example, if you have

$ grep . /sys/class/hwmon/*/name
/sys/class/hwmon/hwmon0/name:nvme
/sys/class/hwmon/hwmon1/name:nct6687
/sys/class/hwmon/hwmon2/name:k10temp
/sys/class/hwmon/hwmon3/name:spd5118
/sys/class/hwmon/hwmon4/name:spd5118
/sys/class/hwmon/hwmon5/name:spd5118
/sys/class/hwmon/hwmon6/name:spd5118
/sys/class/hwmon/hwmon7/name:mt7921_phy0
/sys/class/hwmon/hwmon8/name:amdgpu

you could run

sudo bash -c 'echo 56000 > /sys/class/hwmon/hwmon3/temp1_max'

Thanks,
