Evoker can activate “Press and Tap” instead of “Hold and Release” when casting Empowered spells.

Empowered spells require a second input to complete the cast. Evokers can choose between two options — Hold and Release or Press and Tap to execute the spells.

Hold and Release – Hold and release allows you to begin casting a spell by pressing and holding down your spell key and then release the spell when you release the key.

Press and Tap – Press and tap allows you to tap the spell once to start casting and then tap a second time when you want to release the spell.

 The setting can be found under Accessibility > General.
