The auto tuned value is incorrect post hotplug memory operation, in our use
case memoy hot add occurs very early during boot.
Define incorrect. What are the actual values? Have you tried to

When memory is hotplug added or removed the min_free_kbytes must be
recalculated based on what is expected by khugepaged. Currently
after hotplug, min_free_kbytes will be set to a lower default and higher
default set when THP enabled is lost. This leaves the system with small
min_free_kbytes
