Hello, my answer won't make you happy but seeing the QVL for Ryzen 3000 series CPU there's absolutely no RAM kit mentioned running with 4 DIMMs starting from 3733Mhz except one Corsair kit at 4000 MHz and if I remember correctly you're losing performance (to a certain degree) above 3600 MHz anyway because the FCLK is rated to max at 1800 MHz, and you're supposed to have a ratio of 1:1 with the memory (which means 3600 Mhz)
What you can try anyway is to do a Clear CMOS, go to BIOS, don't use DOCP set up your memory manually in the "Extreme Tweaker" tab, you should start from 2133 MHz and see if it boots. If it does raise a little bit the frequency speed until you can't boot to know what is your max with 4 DIMMs. If you reach 3600 MHz and still can boot, you already did a LOT. If you reach a speed of 3600 MHz or less, and it's bootable/stable you can try to set up FCLK to the corresponding value (you divide the value by two, for ex: DRAM at 3600 MHz = FCLK at 1800 MHz), after this you can tune the timings with your kit timings as a start point (you can find them on the box of your RAM or on the "Tool" Tab there's a tool named "Asus SPD Information")
Of course, if you're not comfortable doing all this, then don't
