We have a FTDI device, FT2232H and an EEPROM M93C46-WMN6TP. Is there a utility or a way to program the eeprom in Linux using command line? We do not have provision for GUI in Linux or for connecting it to a windows system.

There is a sample EEPROM folder provided with the driver package that cab used for programming the EEPROM device (/release/examples/EEPROM/write/ )
Write can be checked used the read program in /release/examples/EEPROM/read/

You can absolutely program an EEPROM with a FT232H, but you will have to write your own program. I am more a Windows person, but the code should similar on Linux.
I just sent a tweet yesterday doing just this with an FT4222 board that I will use for my USB device Nusbio v2. https://twitter.com/MadeInTheUSB/status/808868754146914304
A video experimenting with the FT232H https://www.youtube.com/watch?v=8i8_EFs_j0I
The EEPROM M93C46-WMN6TP protocol seems to be SPI see datasheet page 6
I suppose you may already have an FT232H evaluation board, so once wired on a breadboard to your EEPROM all the 4 SPI wires (CLOCK, MOSI, MISO, CS) you can start talking to the EEPROM. Unfortunately the source code from one EEPROM to another thing can change. I know very well the I2C 24LC256 family and the SPI 25AA1024.
Some of my code is available on github, this is for the SPI EEPROM 25AA1024, that should help

You can find a 100% already made solution hardware and software at
Using the source mentioned above.

I don't see how this is answering the question, regarding a Linux cli tool to program the ftdi
