You should be thinking in terms of watering on an 'as needed' basis, rather than a schedule. Water when a sharpened dowel rod stuck deep into the pot comes out clean/dry. You should be able to water so that at least 10-15% of the total volume of water applied exits the drain hole. If you can't, you need to find a way so you CAN water as described, or take steps to ensure the entire soil volume gets flushed regularly. The goal here is to prevent soluble salts from accumulating and negatively affecting growth and appearance.

Blackthumb. In winter, place your Yucca in the brightest window. Although Yuccas thrive in full sun, they need adapting if placed outdoors in summer.

Water when soil is dry. Yucca is or is very much a succulent, and depending on the soil it's potted it makes a difference..
Then again, since your plant has 3 canes and potted in a 10" pot, the soil will probably dry fairly quick. Hopefully, the container has drainage holes. Toni
