Bed Cargo Tie Down Solution

Greetings fellow Tacomen & Tacwomen:
I have a 2001 sr5 4wd with an under the rail aftermarket plastic bed liner in it. Other than the 4 metal anchor points in the bed, there’s nothing else to secure ratchet straps, rope, or cargo netting too. I know there are solutions to this problem out there, but I’m not sure what a cargo tie down system would be called. I’ve researched the words tie downs, bed rails, anchors, all to no avail. I don’t want to remove the bed liner & install a full on molle system, or install unistrut, as it’s pretty ugly. I’d love to hear what some of you have done or bought to deal with this problem.
