Ventoy does not accept settings from the \ventoy\ventoy.json file on the data section

No. You just need to put all the settings you want in each tab page

e.g.

{
"control":[
{ "VTOY_DEFAULT_MENU_MODE": "1" },
{ "VTOY_LINUX_REMOUNT": "1" },
{ "VTOY_MENU_LANGUAGE": "ru_RU" },
{ "VTOY_DEFAULT_SEARCH_ROOT": "/_ISO" }
],
"control_legacy":[
{ "VTOY_DEFAULT_MENU_MODE": "1" },
{ "VTOY_LINUX_REMOUNT": "1" },
{ "VTOY_MENU_LANGUAGE": "ru_RU" },
{ "VTOY_DEFAULT_SEARCH_ROOT": "/_ISO" }
],
"control_uefi":[
{ "VTOY_DEFAULT_MENU_MODE": "1" },
{ "VTOY_LINUX_REMOUNT": "1" },
{ "VTOY_MENU_LANGUAGE": "ru_RU" },
{ "VTOY_DEFAULT_SEARCH_ROOT": "/_ISO" }
],
"control_ia32":[
{ "VTOY_DEFAULT_MENU_MODE": "1" },
{ "VTOY_LINUX_REMOUNT": "1" },
{ "VTOY_MENU_LANGUAGE": "ru_RU" },
{ "VTOY_DEFAULT_SEARCH_ROOT": "/_ISO" }
],
"control_aa64":[
{ "VTOY_DEFAULT_MENU_MODE": "1" },
{ "VTOY_LINUX_REMOUNT": "1" },
{ "VTOY_MENU_LANGUAGE": "ru_RU" },
{ "VTOY_DEFAULT_SEARCH_ROOT": "/_ISO" }
],
"control_mips":[
{ "VTOY_DEFAULT_MENU_MODE": "1" },
{ "VTOY_LINUX_REMOUNT": "1" },
{ "VTOY_MENU_LANGUAGE": "ru_RU" },
{ "VTOY_DEFAULT_SEARCH_ROOT": "/_ISO" }
],
}

This allows you to have different settings for each mode.
For instance, the search_root folder could be \_ISO_LEGACY for legacy ISOs and \_ISO_EFI64 for efi64 and \_ISO\IEF32 for EFI32 bootable ISOs.
