They should all be there, if the full (not AirPrint) printer driver software was installed correctly, and if one understands where Apple moved the advanced options in the recently redesigned macOS Print dialog box.
To make sure the full (not AirPrint) Epson printer driver is installed, download it directly from the Epson web site; then, when adding the printer using macOS System Settings / Printers & Scanners, do not select any option that says AirPrint because it has fewer, basic options.

If you aren’t familiar with the way Apple redesigned the Print dialog box, the former fiddly pop-up menus are now a more convenient single stack of expandable panels in a resizable Print dialog box. The platen gap and paper thickness options might be under Advanced Printer Control as shown in the demo below. At least that’s where they are for my Epson 3880. The demo below was recorded in macOS 15.2.
I don’t think any of the Epson options were removed. I think Apple simply converted the former pop-up menus into items in the new panel list. Also, if you’re wondering how I resize the Print dialog box out from the center, that’s just the long-time macOS shortcut where if you hold the Option key down while resizing a window, it resizes from the center.
