However, BBC Sport understands the EFL is open to amend the format if it can reach an agreement with the Premier League.
The EFL is disappointed that the Premier League has not agreed to pay more funding to the lesser leagues.
EFL chairman Rick Parry told a Culture, Media, and Sport Select Committee meeting last week that two-legged semi-finals would not be abandoned without a settlement.
“As it stands, there is no agreement in place to make any changes to the Carabao Cup’s two-legged semi-final format, which continues to provide significant financial benefit to EFL clubs,” said EFL chief executive Trevor Birch as the EFL published its 2024-25 schedule on Wednesday.
“The League remains committed to a review of the calendar, but any significant changes cannot be made unilaterally, and would need to come with significant levels of compensation and adopted as part of any new distribution deal with the Premier League and its clubs.”
Even without a settlement, the EFL admits that the tournament will be difficult to schedule.
Because of Uefa’s decision to extend its club competitions to 36 clubs, European matches will now take place in three of the midweeks currently reserved for the EFL Cup.
The EFL Cup semi-final second leg may coincide with a round of Champions League and Europa League fixtures.
