I am using a Microchip MCP2210 USB to SPI converter, however during operation, there is a delay between the sent bytes. Is there a way to remove this ?
You don't say what that delay is, but page 38 of the datasheet (https://ww1.microchip.com/downloads/en/DeviceDoc/22288A.pdf) has settable parameters at offsets 16-19 that may resolve your issues.
A quick scan of the data sheet shows four or five High Byte/Low Byte pairs for registers with the label "Delay Between Subsequent Data Bytes". You should check them all.
