Import CSV limit

-- HikaShop version -- : 6.3.0
-- Joomla version -- : 6.0.3
-- PHP version -- : 8.3.30
-- Browser(s) name and version -- : Opera One(version: 112.0.5197.30)

Hi,
out import CSV limit is stuck at 2M. Where is this set? I've increase it in cpanel for the php version but it isn't tagging across. We've got a ticket in with our service provided but I wanted to check here is there's a way withing Joomla/Hika to adjust the limit.

Thanks,
