Is there any way to reset the level progression?

Question

For example, if I start a game at level 1, and use the console to advance the sneak skill all the way to 100 with player.advskill sneak <huge number>, is there any way to stop the game from forcing me to level up when I enter the skills menu?

Answer 1

The advskill command will count towards the character level up. To get your sneak skill up to 100 without triggering level ups, use the modav command instead to directly alter the skill:

player.modav sneak 100

This adds a +/- for the number. So it'll add 100 to whatever sneak currently is. Alternatively use the setav command:

player.setAV [actor value] [#]

To set it to exactly whatever value you'd like, although I'm sure there are some types of upper/lower bounds. Also, the commands are not case sensitive.

For a list of values you can change, see Actor Values.

Answer 2

This is impossibe to have skill maxed without earning level as far as I know. Skill system is way to connected with character developement and earning levels to change something like that.
