For one computer, i would just go to the policy logs for the computer and flush the last Daily Inventory (or whatever frequency) . The next time the computer checks in with Jamf, it will re-run the inventory policy.
Alternatively, create a policy with just and inventory update with "Once Per Computer" and scope the computer to this policy. Result is the same.
There is nothing more immediate unfortunately. (I have a seen tricks that use profiles and scripts to force an immediate check-in, but I don't remember where I saw it.)
