It shouldn't be possible, no - though I guess if you're using a small sector size, *maybe*? Just because that's not tested too much. And if you're using mods, it'd depend on the mods.
If you open up data/config/settings.json, and set devMode to true, then re-run the game, you can press ctrl-z to turn off sensors. If you're in hyperspace, you'll immediately get intel items for all undiscovered beacons. Make sure to turn devMode back off afterwards, though, it can cause some real problems if you're just playing normally.
