column separator via CLI parameter

I am receiving csv data that I am trying to import via influx-cli. For the life of me I can't understand why one cannot overwrite the default column separator to use e.g. ";" instead of "," via a parameter to the influx write command.
It can't be set via header and has no chance of modifying the parser besides it being the 1st line in the csv.

sep=;

description;some text


timeframe;high;low;total

01.01.2023;0;14;14

02.01.2023;7;4;11

I do have the "sep=;" in the file but I need to skip lines 2,3 and 4. As this is not supported in any way I need to skip all 4 lines and then reinsert "sep=;".

Any other tool I know that does any kind of csv processing allows setting of the separator. Why is this so difficult here?
Or am I missing something entirely and this can be read without having to use awk/sed sort of tools?

Start with the influx-cli `influx write` command and trace how CSV input is parsed, focusing on how command parameters and the first-line separator are handled. Done means a caller can provide a semicolon separator through the command interface and import the shown CSV without preprocessing; add or run coverage for that behavior.
