In-game? No. You can pursue a different track however, which allows you to keep your conjuration skills in reserve while trying a different play style. However if you want to keep the character and reset your skills and perks your only option is to use console commands (and these are only available on the PC).
Alternatively you could keep the character a mage and try something new, like focusing on destruction. Or you could just retire this character and start a brand new one.
