Retirement tax questions

So if they will not release final regulations until 2024, can I wait to see what they do?  I would prefer to postpone payments to the last five years of my 10-year window if at all possible.  IRS pub 590-B for 2022 stated that "The beneficiary is allowed, but not required, to take distributions prior to that date."  I am a designated beneficiary who is not an eligible designated beneficiary.  My details are similar to the original post.  Death occurred in 2021, he had been taking RMD's.  I took his in 2021, then nothing last year or this year.  The company holding the IRA tells me I don't have to take an RMD, another source tells me I do.
