hello to everybody and happy new year!

im having a question, i have a dc-dc step up module witch can provide me with input of 3v output of 3-28v
the thing is that i want to limit this output between 3-15v

is there any way to do it?
the step up module is this one 2 24V to 2 28V 2A DC DC SX1308 Step UP Adjustable Power Module Step Up Boost Converter|Voltage Regulators/Stabilizers| - AliExpress

thank you very much!
