dependent partner Visa expiry before ILR - Extension process

Kindly advise regarding the following: Skilled worker visa now has ILR, but the dependent partner (spouse) is still on the "dependent visa". The visa expires mid July. The spouse needs to extend the visa till end October 2025, before they could apply for ILR.

Please advise:

Question 1: which online link / form should be used for visa extension of the dependent partner / spouse, considering that skilled worker visa holder, now has ILR?

Question 2: is it possible to get extension for less then 3 years, as only few months extension is needed?

Question 3: Would any of the actions reset the clock?

1. Skilled worker dependent visa.

2. No, the immigration rules state it is 3 years, you cannot choose a lesser time.

3. No.

The application form links are here: https://www.gov.uk/skilled-worker-visa/ ... d-children

Thank you. Can you also advise how to address these two questions within the form:

The form asks,

"Does [name] already have their Skilled worker visa?

Option 1: Yes
Option 2: No

If I select yes, it asks for the visa ending date (but the main applicant has now attained ILR and doesn't have a visa expiry date).

If I press no, it takes me to this question: Do you have [name]'s UAN?

Please advise which one is the correct choice. If it is second one, which UAN do I need to put, the one for ILR or previous skilled worker visa?

Say NO. You do not have a UAN either
