I solved the problem myself and did something that i couldn't find online, i edited the V3 2000 BIOS to have the same memory parameter of a velocity, now my V3 velocity behaves identically to a V3, drivers included.
If you want to mod your velocity and never worry again about enabling TMUs and finding weird ass drivers do this:
1: Download the attachment
2: put the folder "Flash utility" on a floppy or any peripheral that can be accessed by your retro PC in DOS
3: Go to DOS and use the flash utility with this command "FLASH Velocity_Modded_2000_8mb.rom"
4:Follow instructions given by the flasher and reboot after it finishes
5:Done, you can install any normal voodoo 3 drivers now.
For commodity, rename the ROM to something shorter like V3MOD.ROM and place it in the same folder with the flasher.
MOD you can change the title to "Voodoo velocity drivers? scratch that! it's BIOS modding time!" at least some other lost souls over the years will find a solution
