How to handle link flapping with routing protocols?

So say you have a crappy link that every 10 min you lose IP reach ability to your peer for ~ 6 seconds.

If you run OSPF / EIGRP its going to flap back and forth all day long. BGP has dampening, but is there any way to basically set a 'backoff' timer for other routing protocols?

e.g. it must maintain its neighbor adjacency for ~5 min before you consider putting traffic back on it?

SD-WAN helps here in WAN scenarios, but I'm just wondering how others take on this challenge.
