No, the leaves are needed to feed the bulb with energy made from photosynthesis. If it isn't already, put the plant in a location in front of a sunny window, or if you don't have good window light, under a grow light so it can photosynthesize enough to store energy. Dormancy is needed to get the plant to rebloom from year to year, which is ideally initiated in late summer or early fall (especially if it spent the summer outside), so might be difficult to do this late in the year. Still, you can learn more about how to care for Amaryllis bulbs, including getting them to rebloom, in the pages linked below:
