Hi there,
I don't think so, but two options as workarounds come to mind.
1) Create a condition where if it's one of the three users, you by-pass the approval task completely and just log an approval manually.
or, if you need that approval formally logged,
2) Create a condition where if it's one of the three users, you go to a secondary approval where the Timeout (in Settings) is set to something like PT4M to time out in 4 minutes, or whatever.
