Since RMD is calculated for a full tax year, it should not make a difference if you take the RMD in a lump sum during the tax year or if you take it on a monthly, quarterly or something else. Since the sum of the smaller payments during the tax year equal the RMD amount if it was done in a lump sum, the income and the tax would be the same.
Thanks again for the question @jf313
All the best,
