Yes, you can request to increase your deposit limit but following these steps:
Navigate to your Account/Wallet section
Scroll down to Player protection section and select "Gaming limits"
Select "Deposit limits"
Select the limit you would like to edit then input the new desired limit
Important information
Any limits set that are more restrictive than the previous limit will take effect immediately
Limits that have been increased (made less restrictive) will not go into effect until after the 30-day cooldown period. After 30 days, you must confirm the new limit from within the app before it can take effect
Once you reach the limit, you will no longer be able to make any deposits in that period.
