Should I choose a different kind of opening when I'm the clear underdog versus when I'm expected to win?

Direct answer
It can be a sensible adjustment, within reason. Facing a much stronger opponent, steering toward a sharper, less mainstream position can raise your practical chances, since forcing more decisions under less certainty helps the side with less to lose. Facing a clearly weaker opponent, a solid, well-understood system that avoids unnecessary risk is usually the better choice, since a long, technically sound game favours the stronger player anyway.
The logic behind playing sharper as the underdog
A quieter, well-known position tends to reward the player with deeper understanding, which is exactly what the stronger opponent already has. A sharper or less common opening forces both players to solve real problems over the board rather than recall preparation, and that narrows the practical gap even if the resulting position is not objectively the safest choice available.
Why the favourite should usually resist the same temptation
A stronger player does not need to gamble. Choosing a reliable opening, developing soundly, and playing patiently lets a real skill advantage show over the course of a full game, while an unnecessarily sharp choice mainly increases the chance of a fluke result going the other way.

Does this mean underdogs should always play unsound openings?
No. The idea is choosing among sound options for the one that is less mainstream or less comfortable for the stronger side, not playing something objectively bad.
Is this a bigger factor in must-win games specifically?
Yes, the pressure to create chances is strongest when a draw or a quiet loss is not an acceptable result.
