Thank you for your quick answer,
We work with C#, and unfortunately, we didn’t find GDALDriverManager API.
Instead, we tried algorithm you proposed with OGR
Driver.DeRegister()/Register() : this does not work, csv change is not taked
into account (csv file seems to be cached)

If your workflow is
open dataset 1
work with it
close dataset 1
change .csv file
open dataset 2
work with it
close dataset 2
then after "change .csv file", you could unload and reload the S57 driver so
that the S57ClassRegistrar singleton gets destroyed and reloaded, with
something like (untested):
GDALDriverManager* poDM = GetGDALDriverManager();
GDALDriver* poDrv = poDM->GetDriverByName("S57");
If you need to operate on 2 simultaneously opened datasets with different .csv
files, then changes would be needed in the S57 driver.
