Kenneth L. Gentry makes a very good argument, I think his book is now open source so it can be found online.
I am pretty sure you will work to refute what he writes, but then that is your choice.

Irenaeus
Irenaeus (A.D. 180), a student of Polycarp (who was a disciple of the apostle John), wrote that the apocalyptic vision “was seen not very long ago, almost in our own generation, at the close of the reign of Domitian” (Against Heresies 30). The testimony of Irenaeus, not far removed from the apostolic age, is first rate. He places the book near the end of Domitian’s reign, and that ruler died in A.D. 96. Irenaeus seems to be unaware of any other view for the date of the book of Revelation.
Clement of Alexandria
Clement of Alexandria (A.D. 155-215) says that John returned from the isle of Patmos “after the tyrant was dead” (Who Is the Rich Man? 42), and Eusebius, known as the “Father of Church History,” identifies the “tyrant” as Domitian (Ecclesiastical History III.23).
Even Moses Stuart, America’s most prominent preterist, admitted that the “tyrant here meant is probably Domitian.” Within this narrative, Clement further speaks of John as an “old man.” If Revelation was written prior to A.D. 70, it would scarcely seem appropriate to refer to John as an old man, since he would only have been in his early sixties at this time.
Victorinus
Victorinus (late third century), author of the earliest commentary on the book of Revelation, wrote:
When John said these things, he was in the island of Patmos, condemned to the mines by Caesar Domitian. There he saw the Apocalypse; and when at length grown old, he thought that he should receive his release by suffering; but Domitian being killed, he was liberated (Commentary on Revelation 10:11).
JeromeJerome (A.D. 340-420) said,
In the fourteenth then after Nero, Domitian having raised up a second persecution, he [John] was banished to the island of Patmos, and wrote the Apocalypse (Lives of Illustrious Men 9).
To all of this may be added the comment of Eusebius, who contends that the historical tradition of his time (A.D. 324) placed the writing of the Apocalypse at the close of Domitian’s reign (III.18). McClintock and Strong, in contending for the later date, declare that “there is no mention in any writer of the first three centuries of any other time or place” (1969, 1064). Upon the basis of external evidence, therefore, there is little contest between the earlier and later dates.https://christiancourier.com/articles/when-was-the-book-of-revelation-written
If he addresses this evidence from these earlier writers and gives a valid reason to question them then I would be interested, but if it is another absurd "it must be before 70 AD otherwise my doctrine is wrong" reason then no thanks, not interested in the clown show.
